brown fused alumina for abrasive

Brown fused alumina is fused with first-class raw materials in 3500KVA arc furnace. It is fused with first-class raw materials in 3500KVA arc furnace, to be used to grind metals such as carbon steel, normal alloy steel, malleable cast iron and hard bronze. It can be used as high-class refractory. Brown fused alumina oxide has high toughness, Micro hardness is 1800-2200kg/mm2, Abrasive articles made of it are suited for grinding metals of high-tensile strength such as steel, annealed, malleable iron and hard high-class refractory products. Useage:brown fused alumina abrasive for grinding, producing polishing materials,casting,producing spraying material and fire-proof material etc. it's widely used in the line of steel, chemical industry and others.
