Product Description

Alumina Insulation Tube/Good Insulation/Electronic Instrument/Innovacera

alumina insulation tube:

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.

Advantages of alumina insulation tube:

1) High dimensional tolerance

2) High heat resistance

Very high wear resistance

Chemical corrosion resistance

Very good thermal conductivity

High degree of reliability and economy in service

Very high mechanical & refractory strength, very hard
