White aluminium oxide

Super fine Grinding media of high purity White aluminum oxide micro powder

White Aluminum Oxide(WA) Super fine powder and micro powder for grinding, abrasive, additive, refractory. It has high purity of AL2O3 99.5%min. #240-#8000, F240-F1200. 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)

 Available Mainly grit of micro powder: FEPA grade F240-F1200, JIS grade #240-#8000, China GB grade W63-w0.5.

Available quantity for each grit: 10MT  to 120MT per month.

Mainly using purpose: grinding, ceramic making, refractory media, abrasive, other additive media. 

It has white color, high hardness (Mohs hardness: 9.0), high melting point(2300 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.
