Product Description
Alumina Ceramic is the most widely used technical ceramic materials.It has high wear resistance, high mechanical strength, high temperature resistance, good thermal shock resistance, excellent electrical insulation. It is usually used for electrical insulators, wear resistant parts, ceramic parts for high temperature furnace etc.
Alumina Ceramic can be made by different purities like 95%, 96%, 99%, 99.5%, 99.7% etc, their properties will have little difference accordingly.
