Comments

Alumina ceramic (Aluminum Oxide or Al 2 O 3) 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.

Elan Technology offers a variety of alumina compositions, including 94% Alumina Low CaO, 94% Alumina High CaO 2, and 85% Alumina 14% SiO 2, 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 Elan Technology are suitable for metallization in order to create a component that is easily brazed with many materials in subsequent operations. Elan Technology offers a range of alumina compositions to meet your most demanding applications.
