1. Description

Alumina ceramic is kind of structural ceramics, with insulation resistance, voltage resistance, high strength, good thermal conductivity, dielectric loss, stable electrical performance characteristics. Used in electronic ceramic substrates, ceramic electrical insulation, vacuum devices, devices porcelain, spark plugs and other products. We can make the part by hot injection pressing, dry pressing, isostatic pressing and extrusion productive technology etc.

Our products with high mechanical strength, hardness, wear resistance, high temperature, chemical resistance and good characteristics. We manufactures custom technical ceramics, covering a wide range of customer requirements.Each product has passed the full(100%) inspection before export, you can safely buy it.
