Silicon Carbide

Ultra light and extremely hard

Sintered silicon carbide (SSiC):

Pressureless sintered silicon carbide (SSiC) is a particularly light and at the same time hard high-performance ceramic. SSiC is characterized by high strength, which remains almost constant even at extreme temperatures. Schunk offers SSiC under the names CarSIK-SD.

What distinguishes CarSIK-SD?

Schunk's CarSIK-SD has a very high resistance to chemical corrosion. Exceptionally high hardness combined with low density is optimal for lightweight solutions.

Where is CarSIK-SD used?

Thanks to its excellent properties, our SSiC ceramic is used in sliding and sealing rings. In personal protection and for the armoring lining of land and air vehicles, CarSIK-SD is also suitable.
