Carbon graphite has a variety of properties, including high electrical conductivity, high thermal conductivity, high temperature resistance, self-lubrication, corrosion resistance, easy oxidation and thermal shock resistance.
Physical and chemical properties
High electrical conductivity: The electrical conductivity of carbon graphite is comparable to that of iron, and it is suitable for applications that require good electrical conductivity.
High thermal conductivity: Its thermal conductivity is close to that of copper, and it is suitable for equipment that requires 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 its lubrication properties decrease in a vacuum dry environment.
Corrosion resistance: It is resistant to corrosion by acids, alkalis and organic solvents, but not resistant to corrosion by strong oxidizing acids.
Oxidation resistance: 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.
