High - Temperature Alumina Ceramic stud
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, 200T isostatic pressing and extrusion productive technology etc.
