White Fused Alumina is also called as synthetic aluminium oxide(WFA),it selects the industrial alumina powder as the raw material,then fused in the electric arc furnace,finally made into different grit size.
This white high purity abrasive is widely used in various industries such as automotive,aviation,medical,dental,cosmetic and flooring etc.

3. Main Application of White Aluminium Oxide in Blasting Applications:
Surface cleaning for metal oxide scale, carbide black skin
Sandblasting for metal or non-metal surface to remove the rust such as gravity die casting mold,oxide scale or agent
removal from rubber molds
Sandblasting the ceramic surface to remove the black spots etc.
Glaze color removal and painting rebirth etc.
In addition, it is also widely used in the following applications of :
Bonded brasives such as resin cutting discs,grinding wheels etc.;
Coated abrasives: abrasive belts, abrasive sheets etc.;
Grinding,polishing and lapping media.
High grade refractories.

What is the white corundum micro powder used for ?
White corundum is made of high quality alumina powder as raw material, which is made by melting and cooling in the high temperature arc above 2000℃. It has high hardness, slightly low toughness, high purity, good self-sharpness and strong grinding ability, and is also used as advanced refractory data. So what is the white corundum micro powder used for?
White corundum powder is made of electrofused white corundum. It has the characteristics of high purity, good self-sharpness, high hardness, slightly low toughness, strong grinding ability, while the white corundum powder is mostly white, small heat value, high efficiency, high temperature resistance, good thermal stability, acid and alkali corrosion resistance and other characteristics.
White corundum micro powder is not only advanced abrasive materials, but also advanced grinding and polishing materials, advanced refractory materials, or a very good insulator, with strong cutting ability, mainly suitable for grinding and polishing fine objects, or do advanced refractory materials.
Due to the special nature of white corundum powder itself, it has become the first abrasive of more and more high-end industries. The grinding tools processed with it are suitable for grinding high carbon steel, high speed steel and all kinds of stainless steel. It is also widely used in fine casting, iron and steel refractory materials, chemical refractory materials, electric porcelain, decoration porcelain and other daily special ceramics.
