Produktbeschreibung

Alumina ceramic components

 

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.

 

Process of production:

uniaxial (die) pressing, isostatic pressing, injection molding, extrusion and slip casting ect.

 

Properties:

* Good electrical insulation
* High mechanical strength
* Excellent wear resistance
* Excellent corrosion resistance
* Low dielectric constant

 

Applicatons:

 

* Special environment and electronic substrates

* Pump seals and other components
* Wear resistant inserts
* Insulating washers or bushings
* Semiconductor components
* Aerospace components
* Automotive sensors
* Electrical or electronic insulators
