White aluminum oxide 5-25 microns (also known as white fused alumina/white corundum 200mesh-0) is an extraordinary refractory powder. It is suitable for investment casting to make shells and molds in the lost foam process.  There are several significant advantages of the powder.

The diamond polishing pad is widely used for flooring polishing.  The main raw material is diamond grain and powder. Adding white aluminum oxide powder can improve sharpness and polishing efficiency. Generally, WFA particle size is smaller than that of diamond particles as the filling of diamond water grinding discs. White aluminum oxide powder 800 # and 1200 # are commonly used grits.

White aluminum oxide F220 is a common grit size for microdermabrasion in the Skincare field. It is a new skin-improvement method that uses the principle of epithelial tissue regeneration to spray microcrystalline particles at high speed to rub the deep layer of the epidermis, stimulate the rapid renewal of collagen and fibrous tissue, and evaporate or destroy skin cells instantaneously.

White fused alumina is shortly called WA. It is a basic abrasive material for cutting wheels and grinding wheels. Compared with brown fused alumina, white fused alumina is more suitable for sharp grinding because WA has a better self-sharpening feature. White fused alumina F60 is a major grit for WA grinding wheel.

The fused aluminum oxide blast media is always for fast blasting operation. The high hardness of about Mohs 9.0 makes it work efficiently for rust removal, surface roughening, and surface cleaning. White fused aluminum oxide is a pure blasting media and ferro-free material. Generally, it blasts in a dry blasting way. In the meantime, it can blast for vapor blasting.

White fused alumina is a kind of refractory powder. It is resistant to the high temperature of hot casting steel liquid. Beside, white fused alumina is of good chemical stability. It is suitable for work as spray powder with lost wax casting process.
