Specifications:  

 1.Desirable Surface Fineness

 2.OEM/OPM Offered

 3.Factory Directly

Productive Technology:

 Alumina ceramic is the special corundum ceramic that has been sintered under 1800°C with the main raw material of Al2O3 and flux of rare metal oxide.Using the high strength organic/inorganic bond to felt together,and then grinding to the size as drawing required.

Advantages:

  1.Heat-resistant

  2.Good insulation

  3.High strength

  4.Precision Process

  5.Wear-resistant

We can produce ceramics according to clients' specifications and even according to 

molds or drawings provided by the client!
