LIGHTWEIGHT PUMP SILICON CARBIDE GASKET RING IN AUTOMOBILE INDUSTRY
Silicon Carbide (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 wear resistance.
Our silicon carbide gasket is useful in a variety of applications including spray nozzles, shot blast nozzles and cyclone components.
