Product Description
Alumina Ceramic is the most commonly used technical ceramic material. Thanks to its very good electrical insulation, dielectric strength and high temperature resistance up to 1500 °C, Alumina Ceramic is ideal for electrical applications and high-temperature applications.
Alumina ceramics feature:
Good mechanical strength
Good heat conductivity and fire resistance
Good corrosion and wear resistance
Very good electric insulation
The alumina substrates also possess several unique features:
> Good surface with high smoothness/flatness and less porosity
> High resistance to heat shock
> Low warpage and camber
> Stable in very high temperature and corrosive chemical
> Very stable breaking strength and shape/dimension variance
Industrial Ceramic Structure Parts Applications:
