Products Description
Silicon Carbide Ball
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 corrosion from acids. Silicon carbide is an excellent ceramic material for applications requiring good erosion and abrasive resistance. Consequently, it is useful in a variety of applications including spray nozzles, shot blast nozzles and cyclone components.
Silicon carbide ceramic balls have a series of properties that metal materials do not have, such as high strength, good wear resistance, high rigidity, corrosion resistance, high temperature resistance, electrical insulation, non-magnetic conduction, and small specific gravity. They are suitable for special ceramic bearing rolling elements.
