BROWN FUSED ALUMINA

Description:

It is made from Calcined Bauxite.

It is 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.

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