Brown Color Aluminum Oxide NKF 180
PRODUCT: Brown Aluminum Oxide
NAME: Brown Aluminum Oxide
Al2O3 CONTENT: 95.0% MIN.
DESCRIPTION:
Brown Aluminum Oxide 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.
