Alumina Ceramic, also known as Aluminium Oxide or Al2O3, it is the one of the most widely used technical ceramic materials. Alumina ceramic components can be manufactured in a range of purities to suit for different applications. Forming methods will vary with the different size, shape and using requirement of products. Alumina ceramics are mainly used for mechanical, electrical, high temperature applications. 

Main Advantages:

*Good strength and stiffness
*Good hardness and wear resistance
*Good corrosion resistance
*High thermal conductivity
*High temperature resistance
*Electrical insulation
*Low dielectric constant
