Global Production

Silicon Carbide (SiC) is one of the most popular high performance tribo-materials, which has been commercially available for more than twenty-five years.

Its features include:
Excellent abrasion and wear resistance
Excellent corrosion resistance· Low coefficient of friction
Low coefficient of thermal expansion
High thermal conductivity
Hardness greater than Tungsten Carbide

Different grades of Silicon Carbide are available as following:
Reaction Bonded Silicon Carbide (RB SiC). a very economical material which gives excellent wear characteristics, as well as good chemical resistance.
Sintered Silicon Carbide (SSiC). the absence of free silicon makes it most resistant to chemically-aggressive fluids, and ideal for high temperature applications.
Graphite-Loaded Silicon Carbide. this is a composite of silicon carbide and free graphite. Graphite is added to RB SiC (RB SiC + C) or SSiC (SSiC + C), to improve tribological behavior by enhanced lubricity.
