Comments

Alumina ceramic (Aluminum Oxide or Al₂O₃) is an excellent electrical insulator and one of the most widely used advanced ceramic materials. Additionally, it is extremely resistant to wear and corrosion. Alumina components are used in a wide range of applications such as electronics, pump components and automotive sensors.

China Glass Ceramic Inc. offers a variety of alumina compositions, including 94% Alumina Low CaO, 94% Alumina High CaO₂, and 85% Alumina 14% SiO₂, but the 96% Alumina Ceramic is one of the most widely used materials.

Alumina components can be formed by a variety of manufacturing techniques such as uniaxial pressing, isostatic pressing, injection molding and extrusion. Finishing can be accomplished by precision grinding and lapping, laser machining and a variety of other processes.

The alumina ceramic components produced by China Glass Ceramic Inc. are suitable for metallization in order to create a component that is easily brazed with many materials in subsequent operations. China Glass Ceramic Inc. offers a range of alumina compositions to meet your most demanding applications.
