Product Description

 

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.
