Product Description

Alumina Ceramic Rings

Alumina Ceramic is the 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. We provide different purity Ceramic what can be fit for the different requirement application area.
