White aluminium oxide

White aluminium oxide grit

White Aluminum Oxide(WA) It has different names in different countries, such as white alumina, Al2o3 powder, white fused alumina etc. FEPA grit, micro powder, JIS powder and grit. It has high purity of AL2O3 99%-99.9%. It’s white color and has little higher hardness and toughness. The abrasive tools made of it are suitable for fine grinding of high carbon steel, high-speed steel and stainless steel. Abrasive powder of finer grit size, can also be used for precision casting and high-grade refractory, for sandblasting, and abrasive etc.


White Aluminum Oxide(WA)

 It is often named fused alumina, alumina. For its high purity of AL2O3, and it is the mainly chemical composition, it is commonly called AL2O3 powder, too. We produce standard grit and powder for abrasive, abrasive media, and special size lumps and powder for refractory, ceramics, additives etc.


The normal grit and powder of white aluminum oxide has white color, high hardness (Mohs hardness: 9.0), high melting point(2200 degree centigrade), high purity (AL2O3:99.5%Min), high temperature resistance characteristic, very stable chemical characteristic.

The powder and grit are widely used for abrasive media, sandblasting, polishing and grinding on metals surface treatment, such as steel, stainless steel, high carbon steel, high speed steel. It is also used for refractory materials, abrasion resistance additive, hardware decoration. And it is commonly used for making ceramics at industrial grade, food grade, for electronics. For beauty additive, it is also commonly in recent years.


The abrasive tools made of it are suitable for fine grinding of high carbon steel, high-speed steel and stainless steel.

Abrasive powder of finer grit size, can also be used for precision casting and high-grade refractory, for sandblasting, and abrasive etc.

 Normal grit including FEPA standard, JIS standard.
