Sandblasted corundum is bauxite. Coke (anthracite) as the main raw material in the electric arc furnace by high temperature smelting, the main chemical is AL2O3, good toughness, was brown. Suitable for sandblasting, sanding, abrasive raw materials, metal casting, grinding and polishing of stainless steel.
