Brown fused alumina with bauxite as raw materials, after melting and crystallization temperature and. It has high hardness, toughness, particle sharp features. Is suitable for the grinding of high tensile strength of metal abrasives tools made of it. Such as: carbon steel, alloy steel, malleable cast iron, hard bronze. Also can be used as refractory materials.
