Carbon graphite is a carbon graphite material element of a class of non-metallic materials. It is the carbon in the three isomers of a, is a hexagonal system, at all levels by the hexagonal rings, parallel level with the level, the overlap was ordered crystal structure.

By source of natural graphite into graphite and artificial graphite. Artificial graphite from carbonaceous materials by high temperature above 2500 ℃ from graphite treatment.

Carbon graphite is generally good conductivity, heat resistance, wear resistance, self lubrication, high temperature stability, strong resistance to chemical corrosion, high thermal conductivity than the polymer, linear expansion coefficient. In the atmosphere and at room temperature with chromium-plated surface friction coefficient and wear rate is very low. However, when the humidity is very low loss of lubrication. Coated carbon graphite wear-resistant coating can improve the wear resistance.

Not only for solid graphite lubricant can be added to the resin, metal, ceramics and other materials to increase the friction of these materials can also be used directly as a friction material, such as paper making, wood processing, textiles, food avoid oil place bearings, high temperature bearings, seals, piston rings, scraper and so on.

Mechanical Engineering with a carbon graphite material "class" represents the sign of M, there are four series: carbon graphite materials, graphite materials, electricity, resin and metal graphite carbon composite material.
