Wear-resistant Alumina Ceramics for Industry

Name:Wear-resistant Alumina Ceramics Structure:Polycrystal Size:Customized Alumina Content:95% or 99% Ce:ISO9001-2008

Specifications:  

  1.Wear-resistant

  2.Desirable surface fineness

  3.OEM/OPM Offered

  4.Factory Directly

Productive Technology:

    Wearable 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.High temperature

   2.Good insulation

   3.High strength

   4.Precision Process

We can produce ceramics according to clients' specifications and even according to molds or drawings provided by the client!
