Product Description

Alumina ceramic (Aluminum Oxide, or Al2O3) is one of the most widely used technical ceramic materials, with an excellent combination of mechanical and electrical properties as well as a favorable cost-to-performance ratio. Wintrustek offers a range of Alumina compositions to meet your most demanding applications. 
 

Typical Grades	95%, 96%, 99%, 99.5%, 99.6%, 99.7%, and 99.8%
Typical Properties	Outstanding electrical insulation  High mechanical strength and hardness Excellent abrasion and wear resistance  Excellent corrosion resistance  High dielectric strength and Low dielectric constant Good thermal stability
Typical Applications	Electronic components and substrates High temperature electrical insulators High voltage insulators Mechanical seals Wear components Semiconductor components Aerospace components Ballistic armor

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

The alumina ceramic components produced by Wintrustek are suitable for metallization in order to create a component that is easily brazed with many materials in subsequent operations.
