Product Name:High Temperature Resistant Refractory Alumina Brick
Product Description:
Products Description

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.


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 Huanya Ceramics 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.
