White fused alumina/WFA is made from high quality alumina by being melted above 2250°C in the electric arc furnace. It is characterized by high purity, great self sharpening, acid and alkali resistance, high temperature resistance and stable thermal performance. Its hardness is a little higher than brown fused alumina. It is with low toughness, great grinding ability, small heat and high efficiency. White fused alumina can be made into all kinds of abrasives, suitable for grinding high carbon steel, high speed steel, stainless steel and other fine-grained abrasives; it can be also used for
precision casting and high-refractory materials.

White Aluminium Oxide has little higher hardness and slightly lower toughness than that of Brown Aluminium Oxide,
that above products features makes it to be used for production of bonded abrasive products for the grinding of the
steels with great hardness, such as high carbon steel, alloy steel, and high speed steel etc.
In addition, it is also widely used in the following applications of :
