Refractory grade BFA Brown Fused Alumina-Used for refractory,casting,foundry and Painting etc
Brown Aloxide 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 refractory.
