Brown Fused Alumina (BFA) is made from Calcined Bauxite. It is a hard and tough material, used in manufacturing of grinding wheels (both vitrified and resin bonded) and coated products. These grains are also used for shot blasting and as polishing media. Refractory grade BFA is used as a raw material in the manufacture of high alumina refractories.
White Fused Alumina (WFA) is made from Calcined Alumina and is a friable product. Like Brown Fused Alumina, WFA is used in the manufacturing of grinding wheels (both vitrified and resin bonded) and coated products. These grains are also used for shot blasting purpose and as polishing media and refractory grade WFA is used as raw material for high alumina refractories.
Addition of chrome oxide to Calcined Alumina gives Pink Fused Alumina (Pink FA). It is not as friable as WFA. It is used in the manufacture of special types of grinding wheels.
