Packing&Delivery

Material characteristics:

1) High temperature resistant type: the melting point of graphite is 3850 ± 50 ºC, and the boiling point is 4250 ºC. Even if the graphite is burned by ultra-high temperature arc, the weight loss is very small, and the coefficient of thermal expansion is also very small. The strength of graphite increases with the increase of temperature. At 2000 ºC, the strength of graphite is doubled.

2) Conductivity and thermal conductivity: the conductivity of graphite is 100 times higher than that of ordinary non-metallic minerals. The thermal conductivity exceeds that of steel, iron, lead and other metal materials. The thermal conductivity decreases with the increase of temperature. Even at very high temperature, graphite becomes an insulator.

3) Lubricity: the lubricity of graphite depends on the size of graphite scale. The larger the scale is, the smaller the friction coefficient is, and the better the lubricity is.

4) Chemical stability: graphite has good chemical stability at room temperature, and can resist acid, alkali and organic solvent corrosion.
