Brown Fused Alumina 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. It is available in grit sizes as per FEPA for
abrasive applications and group grits for refractory applications.
