Structure feature:
Carbon/ graphite is the most widely material, which used on friction pair.It is made of kinds of carbon material( such as hard coke, carbon black, coal, graphite) .Compared with other non-metallic material, possessing good corrosion resistance, it not only has oxido-medium resistance( such as aqua fortis, nitric acid, the dencity above 60% chromic acid, potassium bichromate, Potassium permanganate, and 10% fluorine, 100% bromine and ammonia) , but also has corrosion of any density acid, alkia, salt solutions.It has self-lubricating properties.When the graphtie wear with metalic material, the friction is 0.04-0.05.It has high thermal conductivities.Under 3000 , it has educibility.It has high stablity and low coeffcient of linear expansion in the neutral medium.
