Product Description

Tungsten Carbide (TC) /Silicon Carbide (SIC) Parts

Tungsten Carbide (TC) is one of the most versatile materials available for wear parts.It gives the following benefits:
- High hardness and mechanical strength
- Superior wear resistance
- Good corrosion resistance
- Easily withstands abrasive services
- (Good fracture toughness)


Two primary grades of tungsten carbide are available - Nickel bonded TC and Cobalt bonded TC:
- 6% Nickel bonded TC, gives enhanced corrosion resistance
- 6% Cobalt bonded TC, provides higher hardness and better abrasion resistance
.

psi 261, 000 261, 000

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.
