How to dissolve graphite grease. Graphite lubricant: application, GOST, characteristics. Why graphite lubricants?
The beneficial properties of graphite have been known for centuries. For more than 300 years, it has been actively used to reduce friction in various mechanisms.
The use of graphite as a component of various lubricating compositions significantly expands their capabilities and scope of application.
Despite the emergence of many modern lubricants with higher performance properties, graphite lubricant remains one of the most popular and in demand today in production, in automotive maintenance, and for household applications.
What is graphite grease?
Graphite lubricants (graphite lubricants) mean all lubricants that contain graphite. It can act as additives or be used in powder form as an independent material.
Currently, graphite grease in its traditional form is most widely used. It is a thick, brown to black “ointment” made from oil and a soap thickener. Its main properties were standardized and fixed back in Soviet times by GOST 3333-80 (USsA mineral calcium graphite lubricant).
However, there are many developments that make it possible to use the beneficial properties of graphite as part of other materials - made on the basis of various basic components, as well as in the form of liquid lubricants, aerosols, pastes, and special anti-friction coatings.
Taking into account the synergistic effect of interaction, in addition to graphite, modern lubricants often add other substances (copper, molybdenum disulfide, etc.). Combinations of such materials in certain proportions significantly increase the performance properties of graphite lubricants.
Composition of graphite grease
Traditional graphite lubricant, manufactured in accordance with GOST 3333-80, is obtained by thickening petroleum mineral oil with calcium metal soap and graphite.
Modern formulations can be produced not only in the form of greases.
Aerosol lubricants, for example, are very convenient to apply to hard-to-reach places.
You can often find graphite lubricants in the form of liquid oil dispersions - their formula does not require the use of a thickener.
The composition of graphite lubricant manufactured according to various regulatory and technical requirements may also include other components. For example, using lithium soap instead of calcium made it possible to increase heat resistance to +130 °C and above.
Various additives improve the anti-corrosion, extreme pressure and other performance qualities of the lubricant.
To increase the adhesion of lubricants to metal surfaces, leading manufacturers use polarized graphite instead of regular graphite.
Characteristics
The characteristics of graphite lubricant are determined by the properties of the components present in the material.
Graphite is one of the forms of existence of carbon. It has a layered structure.
Graphite particles fill and smooth out micro-irregularities in the surface of the lubricated part, forming a kind of film on it. Thanks to this alignment and the formation of a graphite layer, the effective contact area of the parts increases. At the same time, the load-bearing capacity of the lubricant increases, and the friction coefficient is significantly reduced.
The oils included in any graphite lubricant ensure optimal operation of components in friction modes, when the surfaces of the parts are separated by a layer of liquid lubricant.
The addition of graphite to the composition of greases gives them additional improved properties, allowing them to better remain in the friction zone and withstand high loads.
The cost of graphite is low, which is why lubricants based on this material are among the most affordable lubricants.
Thus, graphite lubricants have the following main characteristics:
- increased load-bearing capacity
- improved anti-friction properties
- water resistance
- excellent adhesion
- antistatic properties
- good combination of efficiency and cost
The heat resistance of graphite lubricants mainly depends on other components of the composition. Thus, materials made on the basis of calcium or lithium soaps are operational from -40...-30 to +70...+130 °C. Anti-friction coatings with graphite provide protective and lubricating properties up to several hundred degrees.
Graphite has good electrical conductivity. When its concentration is sufficiently high in lubricants, they can also have electrically conductive properties.
However, the structural features of graphite should be taken into account - under normal conditions there are molecules of water and oxygen between the layers of its particles. This causes a decrease in the lubricating properties of graphite lubricants in a vacuum.
The disadvantages of these lubricants also include restrictions on their use in high-speed mechanisms and assemblies with high precision in the manufacture of parts. In these cases, graphite particles disrupt the contact geometry, which leads to accelerated wear of parts.
Scope of application of graphite lubricant
Where is graphite grease used?
The scope of application of such lubricants is huge - they are used both in industry and in domestic conditions. In many cases, these materials also turn out to be an excellent solution for servicing heavy construction, road, special, oil-producing, and agricultural equipment.
Traditional graphite lubricants are used to service highly loaded friction units of low-speed mechanisms:
- lead screws
- hinges
- sliding supports
- guides
- threaded connections
- gearboxes
- bearings
The use of thickeners and other types of liquids instead of calcium soap and mineral base oil makes it possible to increase the heat resistance, speed characteristics and other performance properties of graphite lubricants and significantly expand the scope of their application.
Oil dispersions can be used independently - in this case, graphite particles easily reach even hard-to-reach friction zones - or as additives to other commercial oils.
Automotive Applications
The scope of application of graphite lubricant in automotive technology remains quite wide even now, when many materials with higher performance properties have appeared on the market.
The extreme popularity is explained simply - “graphite” can be purchased almost everywhere, used for most components, and at a cost it is much more attractive than modern materials.
Application examples:
- leaf springs to reduce friction and eliminate squeaking
- wheel nuts, studs, bolts - to prevent jamming
- cable drives – for smooth running and reduced wear
- base of the retractable antenna pin - to eliminate crackling and rustling noises when receiving a radio signal
- protection of electrical connections and contacts from corrosion
- suspension and steering components (steering joints, racks, gears, ball joints, anti-creaking washers, etc.)
- threaded connections of body parts and suspension
- caliper guides and anti-squeak plates for disc brakes
- cardan crosspieces in rear-wheel drive models
- door hinges, lock mechanisms
- seat guides
- jacks
- car coupling devices
- CV joints
The use of graphite lubricant in a car is not limited to the examples given. Almost everywhere where there are loaded mechanisms with low speed, it will be very useful.
Industrial Application
The use of graphite lubricant in industrial production ensures high reliability of components and mechanisms, extended service intervals and excellent operating properties of equipment.
Mineral- and synthetic-based graphite lubricants are widely used in a wide variety of industries.
Examples of industrial equipment components for which graphite lubricants are used:
- Drill bit supports in the oil industry
- Units of special equipment, agricultural and industrial equipment operating in conditions of dust and other abrasive contaminants
- Open gears of material handling equipment, bulk material mixers
- Shut-off pipeline valves
- Low speed bearings
- Open and closed shafts
- Rolling and sliding supports for drying chambers and ovens

- Conveyor chains
- Bearings and gears for electric and pneumatic tools
- Bearings and gears for centrifuge drives
- Spindles of tinting machines
- Trawlers winches
- Screw pairs of machine tools
Household applications
Graphite lubricants are also used in everyday life. Good owners use them to lubricate door hinges and locks, for maintenance, repair and storage of electrical and mechanical tools, bicycles, etc.
Thus, we are convinced that lubricants with graphite are effective, inexpensive means for protecting contacting parts from wear, friction, corrosion and increasing their service life.
The use of these materials in the listed units, as well as for many other applications, will be a successful solution to many problems in the repair, maintenance and storage of industrial and household equipment and vehicles.

What is graphite lubricant?
The first graphite lubricant was made from a mineral base oil thickened with graphite and calcium soap. Calcium soap provided the material with good resistance to being washed off with water. The finished product was a homogeneous black to dark brown ointment. Today, graphite lubricants are any lubricant that contains graphite, such as graphite-infused oils, anti-friction coatings, greases, etc.
Graphite lubricant has a great advantage - durability. After the oil film stops working, the hard graphite particles protect the assembly surface from boundary friction, corrosion, scuffing, seizing and contact with abrasives.
Traditional graphite lubricants operate at temperatures from -20 °C to +70 °C. They are designed for servicing loaded mechanisms made of steel or copper alloys that are prone to oxidation (threaded connections, gears, lead screws, jacks, car suspension elements, etc.).
The use of graphite lubricant in automotive equipment is especially important, for example, in order to reduce friction between leaf springs, to lubricate the parking brake cable, the retractable antenna of a car (removes interference during the operation of the radio). In everyday life, door hinges can be treated with graphite lubricant to protect metal surfaces and eliminate squeaking.
Graphite lubricant. Properties
The performance characteristics of traditional graphite lubricants meet the operating conditions of equipment and machinery produced in Russia. Compared to conventional lubricants, graphite lubricants have the following advantages:- High anti-friction characteristics
- Increased load-bearing capacity
- Provides smoother running of mechanisms
- Improves lapping of metal parts
- Conduct electricity
- Moisture resistance
- Low melting point of calcium thickener reduces upper operating temperature limit
- Due to the coarsely refined, coarsely ground graphite, the field of application is limited to open components with poor surface quality
One of the discoveries of engineers is the synergistic interaction between graphite and molybdenum disulfide (MoS 2). It is based on replacing the weaknesses of one substance with the strengths of another. Thus, graphite performs poorly in a dry environment and unsatisfactorily in inert gases. Molybdenum disulfide, in turn, shows weak properties in a humid environment.
When combining graphite powders and molybdenum disulfide, a mixture is obtained that significantly exceeds the characteristics of each of these materials separately.
Application of graphite lubricants
Graphite is an excellent anti-friction filler, so graphite lubricant is ideal for servicing large and small mechanisms.The scope of application of graphite lubricants is large. As a rule, they are used to service components and mechanisms operating under heavy loads - in oil production, automotive, construction, and agricultural machinery. In addition to protecting against wear, the lubricant prevents squeaks caused by friction of parts. In low-speed gearboxes, “graphite” softens the contact of gears by absorbing the energy of the impact interaction of the teeth.
In everyday life, graphite lubricant is used to protect garage and door hinges, locks, etc. Due to its good water resistance, the material does not require frequent replacement.
Graphite lubricant is most popular when servicing vehicle components.
- Ball joints and suspensions
- Steering knuckle bearings
- Gears and steering racks
- Threaded connections
- Battery terminals
- Cardan crosspieces on a rear-wheel drive car
- Brake caliper guides
- Anti-squeak washers in springs, etc.
It should be noted that graphite lubricant is not suitable for all vehicle components, since graphite, for example in small bearings, can cause premature wear.
Advanced materials MODENGY and EFELE are an ideal replacement for traditional graphite lubricants!

Graphite lubricant is a very popular material that is used everywhere: from heavy industry to passenger cars.
Polarization allows the characteristics of graphite to be enhanced, i.e. polarizing agents are introduced into the layered structure of graphite. This is how polarized graphite is obtained. It works in humid environments, has greater adhesion to metal surfaces and is thermally stable. Today it is one of the most promising solid lubricants.
Due to its high performance properties, graphite, as an additive, can be used in almost any type of lubricants, enhancing their characteristics. Moreover, its presence in the composition practically does not increase the final cost of the product.
Graphite lubricants, originally produced for lubricating parts of low-speed mechanisms, are becoming increasingly widespread in technology due to their unique properties.
The characteristics of graphite lubricant are determined by the components of which it is composed. The composition of graphite lubricant (outdated name “graphite USsA”) in Soviet times was established by GOST 3333-80.
A simplified description of its manufacture looks something like this: a synthetic or organic viscous oil (derived from petroleum) is thickened by adding calcium soap and graphite powder. To simplify it as much as possible, solid oil is mixed with crushed graphite.
Crushed graphite
Graphite (crushed carbon), which forms the basis of graphite lubricant, is able to fill microscopic irregularities in parts, while reducing friction.
The use of a material such as graphite in the lubricant is not accidental - it was used to reduce friction between parts 300 years ago. Graphite, as you know, is nothing more than carbon (coal), but in a more “loose” state, as a result of which it is able to fill microscopic irregularities in parts (scratches, cavities, marks from cutting and processing tools, etc. ). This “smoothing” of surfaces significantly reduces the coefficient of friction.
Solid oil provides liquid friction of parts - in general, it works like any other lubricant, but in combination with graphite, it allows the latter to remain in the friction zone of parts - shafts, gears, etc.
Pros and cons of graphite lubricant
The fusion of the features of solid oil and graphite as lubricants gives graphite lubricant the following properties:
- Temperature range of use: – from -20 to + 70 degrees. For heavily loaded mechanisms, the lower limit can be increased - where friction losses do not significantly reduce the efficiency of the machine.
- The lubricant has good water-repellent properties.
- Great .
Modern lubricant production technologies have made it possible to industrially produce high-temperature graphite lubricants with an expanded temperature range for its use - from -40 to +400 degrees.
The disadvantages of “graphite” include the limited use of it in assemblies with high precision manufacturing of parts and high speed of their interaction - solid impurities contained in graphite will contribute to premature wear.
Thickening base of graphite grease
Solid oil based graphite lubricant
The most common graphite lubricant is made on the basis of solid oil, this allows it to reduce its cost and maintain its lubricating properties.
The most common graphite lubricant in its usual form is a thick gray grease. But now it is also available in aerosol form, which makes it more convenient to apply it in a thin layer. There is also a copper-graphite spray lubricant on sale, with the addition of copper powder - we’ll talk about using it in a car a little later.
Depending on the area of application of the graphite lubricant, you can currently choose a suitable composition - the main difference between the types of such lubricants is the substance that plays the role of an oil thickener, which can be:
- Hydrocarbon.
- Organic.
- Inorganic.
- Soapy.
Making graphite lubricant with your own hands currently makes sense only in terms of satisfying curiosity - commercially available lubricants are inexpensive, and purity and fine grinding of graphite can only be achieved with a fair amount of effort. However, to prepare “graphite” for household needs, it is enough to thoroughly mix the graphite powder with any grease - from lithol to CV joints.
Purpose and use of graphite lubricant in technology
Copper-graphite grease application
Graphite lubricant is used everywhere where high dimensional accuracy and speed of rubbing surfaces are not required.
What is graphite lubricant used for? The scope of application of graphite lubricant is quite wide - it is used in mechanisms operating under heavy loads - in agricultural, construction, automotive, and oil production equipment.
In addition to protecting against wear of mechanisms, “graphite” allows you to get rid of squeaks caused by friction of parts.
Its use in low-speed gearboxes makes the contact of the gears “softer” - the grease partially absorbs the energy of the impact interaction of the teeth, which protects them from destruction.
To facilitate the maintenance of mechanisms in production, a pneumatic or hydraulic gun is used for graphite (or any other grease) lubrication. But to service a small number of lubrication points, a regular grease syringe, familiar to many car owners, is sufficient.
Graphite lubricant in everyday life
In everyday life, the lubricant is used to protect locks, door and garage hinges - it has good water resistance and does not require frequent replenishment of the required amount.
The use of graphite lubricant instead of thermal paste is still experimental in nature - the thermal conductivity of graphite is not the same in different directions and for maximum heat transfer it is necessary to somehow orient the graphite grains in a certain way. And the composition of graphite also affects its characteristics.
Graphite lubricant in a car
Injection of steering joints with graphite grease
What can be lubricated with graphite lubricant in a car? Here are the most common uses:
- lubrication of steering joints, steering mechanisms (except for those that use transmission oils - the latter have higher extreme pressure properties);
- lubrication of ball joints;
- protection of electrical connections from corrosion;
- Lubricating anti-squeak washers in springs.
In automobiles, graphite is used to lubricate steering mechanisms, ball joints, and protect electrical connections from corrosion.
You can also lubricate the calipers, or rather their guides, with graphite grease.
To prevent brake drums and discs from “sticking” to the hub flanges, copper-graphite aerosol lubricant is ideal - you just need to avoid getting it on the working surfaces or immediately wash it off with a degreasing compound.
Aerosol graphite lubricant
Applying lubricant to the threads during assembly after repair will make it much easier to remove bolts and nuts during subsequent repairs.
In addition, applying lubricant to the threads during reassembly after repair will make it much easier to remove bolts and nuts during subsequent repairs.
Some car enthusiasts are interested in whether it is possible to lubricate bearings with graphite grease. In general, “graphite” is not yet used in the manufacture of sealed bearings - apparently, at the moment the use of graphite in the lubrication of high-precision parts is limited, but it is impossible to say that this will continue to be the case - the development of new lubricants does not stop. But for now, in this case, the question of which is better: lithol or graphite lubricant, we can answer that using lithol is more preferable.
Treating the exhaust pipe with graphite lubricant
Motorists even used graphite to protect exhaust system parts during times of general shortage. Lubricant was applied to the new muffler, on which, after the grease burned out, a strong protective crust formed, not afraid of water and resistant to deep scratches from branches, small stones and sand.
Does graphite grease conduct current or not?
On power electrical contacts, graphite does not create additional resistance.
When protecting electrical connections, it does not create additional resistance, unlike other lubricants, so it can even protect power contacts - for example, when connecting the “positive” wire to the starter. This is a very important point - protecting the contact with a poorly conductive coating can lead to its heating and fire of the wiring.
Graphite Lubricant Manufacturers
Graphite grease in a tube
Considering the growing scope of application of graphite lubricant, it is produced by almost all oil manufacturers, including the Felix company, which offers both Felix high-temperature graphite lubricant and general-purpose graphite lubricant.
Also common on the market are graphite lubricants from Oilright Oilright, which produce their products in different packaging - from 100 g to 180 kg.
The average price of domestically produced graphite lubricant is approximately 70 rubles per kilogram (or per liter container weighing 800 g).
Car care and prevention of all kinds of malfunctions means, first of all, checking the presence of oils and lubricants in all working components of the machine, as well as their timely replacement or replenishment. Regular replacement of lubricant is the main guarantee of durability of both the car as a whole and its individual parts, especially those that are subject to friction.
One type of lubricant used in cars is graphite lubricant. In this article we will talk about what kind of lubricant it is, what its properties are and where it is used.
All types of lubricants are divided into four categories:
- organic;
- inorganic;
- hydrocarbons;
- soapy
Belonging to one category or another is determined by the composition of the lubricant thickener, which also determines its basic operational properties. In this regard, graphite lubricants are synonymous with inorganic lubricants. In addition, “graphite” refers to lubricants that contain graphite, which most often acts as an additive. Graphite powder can also be used as an independent lubricant.
Characteristics of graphite and graphite lubricants
Graphite itself is familiar to most of us. This is a black solid substance, which is distinguished by fairly high thermal conductivity and electrical conductivity. Graphite also withstands high temperatures without changing its structure, which makes it possible to use it in various operating conditions.
The beneficial properties of graphite in its pure form are also preserved when it is added to various types of lubricants. The positive quality of graphite lies in the behavior of its molecules, which are almost not attracted to each other, but at the same time combine well with metal oxides. Thanks to this property, a firmly seated protective film is formed on the surface of metal parts treated with graphite lubricant, which helps neutralize friction forces.
Another advantage of graphite lubricant is its high durability due to its double action. Firstly, the protective film prevents friction. Secondly, even when the protective film is destroyed, the graphite particles themselves act as an anti-friction substance, protecting parts from friction and its harmful consequences.
Thus, for all types of graphite lubricants, the following beneficial properties inherent in them can be distinguished:
- low cost with fairly high efficiency;
- heat resistance, allowing the use of mechanisms in a wide temperature range;
- double anti-friction action (the main lubricant is petroleum oil and graphite as a filler);
- chemical neutrality, allowing the lubricant to be used for parts made of various materials without fear of negative consequences.
When storing lubricants containing graphite, it is recommended to avoid exposing them to direct sunlight, which worsens their anti-friction properties.
The use of graphite lubricants in a car
Graphite-based lubricants can be used in various fields of technology where it is necessary to ensure smooth interaction of mating metal elements. It is especially recommended to use graphite lubricants in components operating under heavy mechanical loads, as well as during the period of grinding in parts in new or repaired mechanisms.
Thanks to the above beneficial properties, graphite lubricants are effectively used in vehicle maintenance. Since this lubricant is capable of functioning at temperatures from minus 30 to plus 120 degrees Celsius, it can be used in almost all latitudes of our country.
An indispensable assistant for a motorist are graphite lubricants used in the following automotive components:
- suspensions and ball joints;
- steering knuckle bearings;
- steering racks and gears;
- universal joints for rear-wheel drive vehicles;
- various threaded connections;
- battery terminals.
It should be noted that in some components the use of graphite lubricant is undesirable, since graphite particles have slight abrasive properties and can cause premature wear of small bearings.
For the above automotive components, graphite lubricants can not only extend service life, but also ensure smooth interaction, get rid of extraneous sounds and noise, and reduce production. In threaded connections, such a lubricant prevents corrosion and sticking, which in turn greatly facilitates the disassembly of components and preserves the service life of parts for a longer period.
The general rule for using graphite lubricant in a particular automotive component is to follow the recommendations of the vehicle and lubricant manufacturers, as well as the expert opinions of specialists in this field. With the reasonable use of this type of lubricant, both the car as a whole and its most vulnerable parts will serve its owner much longer than without their use.
Graphite lubricant is obtained by processing petroleum oil, for which the so-called calcium soap is used. The result of such processing is a thick ointment. Currently, graphite lubricant, used in a car, which helps reduce friction, is presented in various names.
With the increase in the number of cars, the composition began to be used much more actively than during its discovery at the dawn of the automotive industry. In addition to choosing between different licensed brands, there is the possibility of making it yourself.

Lubricant characteristics
Externally, graphite lubricant resembles a thick cream of brown or dark color. The characteristics of different types of lubricant differ, primarily regarding the minimum temperature at which it begins to freeze. In most cases this occurs at minus 20 degrees Celsius. When this threshold value is reached, it begins to thicken, and therefore the friction between individual elements in the car increases.
There is another threshold - the maximum positive temperature, which is on average 70 degrees.
Azmol graphite lubricant
It is necessary to pay attention to the fact that graphite lubricant has good contact only with metals susceptible to oxidation. In some cases it can be used for processing precious metals. This use is atypical and will not bring the desired result. If we consider the interaction of a substance with metals in a car, then in this case a reduction in friction is achieved due to the presence of water molecules between the individual layers of graphite. The weak connection of the elements reduces the friction of parts with each other, which is why lubricant has become so widespread in industry.
Ready to use graphite grease Application of lubricant
For the first time, petroleum-based substances were used to treat individual parts of lifting devices. Subsequently, with the development of technology and the emergence of new methods of oil refining, its use became more active. In any car, a significant part of the fuel energy goes to overcome the friction force. In addition, too much contact between parts increases their wear, and accordingly, the cost of servicing the machine increases. Using one of the types of lubricants on the market, the car owner reduces fuel consumption and wear of the mechanism.
Diagram of a bicycle where the lubricant mixture is used With the use of graphite, friction between the leaf springs is reduced, and the movement of the parking brake cable is also improved. In addition, motorists use the substance to lubricate hinges and improve the operation of the radio. The latter is achieved by lubricating the contact point - thanks to this, it is possible to cut off unnecessary interference and restore the previous level of signal reception.
In the absence of licensed lubricants, substitutes are sometimes used, however, their freezing point is often above 20 degrees, which is not always acceptable. Therefore, not everyone undertakes to make their own lubricants. One of the important conditions here has always been maintaining the correct proportion of source materials. So, for 500 grams of solid oil there are 100 grams of gear oil and graphite powder. Before mixing, the solid oil must be heated to 50 degrees. Heating is necessary for rapid dissolution of other components in the grease.
