Custom industrial alumina ceramic sleeve

Specifications Material: Alumina ceramic

high Density: above 3.9 g/cm3

high mechanical strength.

Good chemical corrosion resistance

Custom industrial alumina ceramic sleeve Material: 99% Alumina ceramic high Density: above 3.9 g/cm3.   Advantage of industrial alumina ceramic sleeve. 1.Aluminum Oxide offers good thermal conductivity 2.High temperature capabilities 3.Wear-resistant, very hard 4.High strength and stiffness 5.Resistant to strong acid & alkali 6.Excellent dielectric properties from DC to GHz frequencies   Alumina ceramic is the most widely used advanced ceramic material. It has the advantage of good insulation good chemical corrosion resistance and melting properties, small thermal expansion coefficient, mechanical strength, good thermal conductivity characteristics.     Industrial Alumina ceramics sleeve is mainly used in biological ceramic, wear resistant materials such as ceramic ball and rod, mechanical parts, such as sealing ring, ceramic valve, high temperature device, such as high temperature liquid delivery pipe, electronic devices such as high voltage switch tube shell insulation material and so on.
