Brown fused alumina abrasives
Description:
It is made from Calcined Bauxite.
It is hard and tough material, used in manufacturing of grindingwheels (both vitrified and resin bonded) and coated products.
These grains are also used for shot blasting and as polishingmedia.
Refractory grade BFA is used as a raw material in themanufacture of high alumina refractory.
It is available in grit sizes as per FEPA for abrasiveapplications and group grits for refractory applications.
