Brown Aluminum Oxide HS Code 28181010, CAS No. 1344-28-1, 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 brown aluminum oxide 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 section sand for refractory applications.
