Alumina C799 is a very hard, dense material of exceptional strength.  Alumina ceramic exhibits resistance to both high temperature and corrosion. Electrical properties of alumina ceramic aluminum oxide include high volume resistivity as well as low loss characteristics at high frequencies. We produce many grades of Alumina Oxide Ceramic products by injection molding, dry pressing and extrusion processes. By using these processes and different chemistry, alumina ceramic properties are enhanced to meet most engineering requirements. Applications for alumina oxide ceramic include pump seals, temperature sensors, knife sharpeners and refractory anchors.
