High Quality Brown Fused Alumina for Resinoid (A-B)/Abrasives Sandblasting

Brown Fused Alumina (A-B)  is mainly produced by bauxite which smelting in an electric arc furnace at high temperatures, it is brown and featured high hardness. With equal volume of particles and strong toughness,brown fused alumina is suitable for manufacturing of resin cutting and grinding wheel, especially suitable for high-speed grinding wheel and cutting disk, which can act on cast iron, regular steel, carbon steel and nonferrous metals such as hard bronze.
