WHITE FUSED ALUMINA USED FOR GRINDING WHEEL MANUFACTURING AND REFRACTORY USERS
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.
