99.5% Alumina ceramic bush

99.5% Alumina ceramic bush Material: 99.5% Alumina ceramic/99.5% al2o3 ceramic high Density: above 3.9 g/cm3. Wear resistance and high temperature   Advantage of alumina ceramic Bushing.  1.Alumina ceramic  bushing 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. Alumina ceramic bushing 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.
