Silicon Carbide Gasket

Edgetech Industries, Advanced Ceramics Division supplies high-quality and competitive price advanced Silicon Carbide (SiC) Gasket.


Silicon Carbide Gasket, SiC Gasket


Silicon carbide (SiC) is a lightweight ceramic material with high strength properties comparable to diamond. It has excellent thermal conductivity, low thermal expansion, and is resistant to acid corrosion. Silicon carbide is an excellent ceramic material suitable for applications requiring good corrosion resistance and wears resistance, such as gasket.

Our silicon carbide gasket is useful in a variety of applications including spray nozzles, shot blast nozzles, and cyclone components.
