Advance Technical Ceramic Wear Resistant Alumina Ceramic Plate
Description:
Alumina ceramic is with superior strength, hardness, insulation,
thermal conductivity, high temperature, oxidation resistance,
corrosion resistance, abrasion resistance, high temperature
strength and other characteristics. It has been widely used in
engineering, mechanical seals, electronics, intrumentation,
sensing, transport, communications,and other occasions or areas.
The content of 99.7%, 99.5%, 99%, 96% alumina products contain the
crucible, sockets, valves, electrodes, spools, wear board, alumina
balls, rings, electronic porcelain, textile porcelain pieces and
other shaped pieces.
