brown fused alumina perfect polishing materials precision sand mold high refractory materials abrasive materials

Brown fused alumina is made by alumina as raw material, which is meited at high tempreture.

 Brown Aluminium Oxide

The abrasive tools that made from it are suitable for the grinding of high carbon steel, high speed steel and quenching steel.

 They are also used as polishing materials and precision sand, mold casting, spraying abd coating materials, chemical catolyst carrier, soecial ceranics  and high refractory materials.
