Carbon graphite has a variety of technical characteristics, mainly including high electrical conductivity, high thermal conductivity, high temperature resistance, self-lubrication, corrosion resistance, easy oxidation, thermal shock resistance, etc.
High conductivity: The electrical conductivity of carbon graphite is equivalent to that of iron, and it is suitable for application scenarios that require good electrical conductivity.
High thermal conductivity: Its thermal conductivity is close to that of copper, and it is suitable for occasions that require efficient heat dissipation.
High temperature resistance: Carbon graphite is one of the most high-temperature resistant materials. It has no melting point at room temperature and begins to sublimate at 4000℃.
Self-lubrication: It has good lubrication properties at a certain humidity, but the lubrication properties decrease in a vacuum dry environment.
Corrosion resistance: It can withstand corrosion from acids, alkalis and organic solvents, but is not resistant to corrosion from strong oxidizing acids.
Easy oxidation: It begins to oxidize in hot air at 450℃.
Thermal shock resistance: The thermal expansion coefficient is small, and it is not easy to produce cracks and damage due to rapid temperature changes.
In addition, carbon graphite also has the characteristics of low friction coefficient, wear resistance, and low linear expansion coefficient, making it a sealing material with excellent comprehensive performance.
