More info

Zirconia Ceramic Disc is a high-performance ceramic material known for its high strength, corrosion resistance, high-temperature resistance, non-conductive nature, and electrical insulation. It is made of high-purity and ultrafine raw material powder by pressing, injection molding, or extruding, and then sintered at high temperature to form blanks, polished, chamfered fine grinding, and other finishing processes. HM can supply high-precision and competitively priced Zirconia Ceramic Discs with various specifications according to drawings.
