99% Alumina parts
Alumina ceramic is a type of wear-resistant technical ceramic that provides excellent mechanical and electrical performance. Alumina ceramic features high hardness, wear resistance, low erosion, high temperature resistance, corrosion resistance, and biocompatibility. It is often made into valve seats, semiconductor device parts, insulators, etc. Junjie provides various types of alumina microporous ceramic suction cups, wafer handling arms, and semiconductor equipment components for the semiconductor industry.
