Silicone Carbide
Silicone Carbide is the execellent material among the secondary frictional materials. The frictional factor of the combination of silicone-carbide and carbon-graphite is the least.So silicone carbide is widely applied to components of high-temperature heat engine, abrasion resistant fields of automobile, astronavigation, shipping etc.
