Alumina ceramic custom
parts
Description:
Alumina ceramic, Al2O3
aluminium oxide ceramics is an advance ceramic materials which used
for the industry.It has excellent material properties over
metal.Aluminum oxide ceramics
is very hard and resistant to wear, providing high compressive
strength even in extreme temperatures and corrosive
environments.Alumina is also an excellent electrical insulator and
gas tight.
Typical Alumina
property include:
