Brown corundum F80 F100 F120 for iron parts sandblasting and rust removal
PRODUCT: Brown corundum
NAME: Brown corundum
Al2O3 CONTENT: 95.0% MIN.
DESCRIPTION:
Brown corundum 80# 100# 120# for iron parts sandblasting and rust removal 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.
