Product Description

Alumina is historically the most cost effective and widely used engineering ceramic. It has a good combination of properties:
- Good hardness and wear resistance
- High strength and stiffness
- Good thermal stability
- Almost chemically inert

Alumina can be produced in purity ranges from 95%, up to 99.5% (available in ivory color), for various applications.
