Product Description

Brown fused alumina (A) is produced by fusion of bauxite in an electric arc furnace at high temperatures. The brownish coloured product shows high hardness as well as extreme toughness. The materials are used to grind metals of high-tensile strength such as steel, annealed malleable iron and hard bronze. It can also be used as high-class refractory.
