Product Description
99% Alumina Ceramic TUBE
1. Alumina ceramic
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.
Alumina ceramic thermocouple-protection tubes are considered to have better mechanical strength and better chemical resistance.Alumina ceramic thermocouple-protection tubes also have excellent abrasion resistance. Alumina ceramic thermocouple-protection tubes are considered to be gas tight so they make excellent primary protection tubes.
