Our main products as follows:
Graphite material advantage features:
1, High Temperature: Graphite is one of the most high temperature materials. The melting point of graphite is 3850°C±50°C and its boiling point is 4250°C. The high temperature resistance of graphite is very good.
2, Special Thermal Shock Resistance: Graphite has a good thermal shock resistance, that is, when the temperature changes abruptly, the thermal expansion coefficient is small, so it has a good thermal stability, without crack in the temperature change of rapid cooling.
3, Thermal Conductivity and Conductivity: Graphite has good thermal conductivity and conductivity. Compared with general materials, its thermal conductivity is quite high. It is 4 times higher than stainless steel, 2 times higher than carbon steel and 100 times higher than normal non-metal materials.
Graphite lubrication depends on the size of graphite scales, the greater scale, the better lubricating.
5, Chemical stability: At room temperature, graphite has good chemical stability and is resistant to acid, alkali and organic solvents.
6, Plasticity: Graphite toughness is good, can be crushed into thin slices.
