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.
