Product Description

Alumina is a very hard and dense material, it exhibits resistance to both high temperature and corrosion with a simultaneous high mechanical strength, which is why it can be used at high temperature applications of up to 1700 °C. 

 

 

The excellent electrical insulation strength helps aluminum oxide ceramics become a leading material for high voltage applications such as gas ignition.

 

 

Almost all shapes are available. In case of dirt adhesion during use, alumina can also be glazed.

 

 

The application of aluminum oxide ceramics can be everywhere, it is the aluminum oxide that is the number one in terms of application depth and popularity, like substrates and resistor cores in the electronics industry, thread guides in wire and cable engineering, seal and regulator discs for water taps and valves, heat dissipating elements for lighting systems, protection tubes in thermal processes and catalyst carriers for the chemicals industry.
