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.  

Alumina ceramics 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.

We can custom made by your drawing. Small order can be acceptable.
