Brown Fused Alumina is fused and crystallized under high temperature from mixture of bauxite and other materials, characterized by its high hardness, good toughness and sharp shape in particles. Abrasive tools made of it are suitable for grinding metals of high-tensile strength such as carbon steel, general purpose alloy steel, malleable cast-iron and hard bronze etc. It also can be used as refractory materials. For refractory materials, RS Brown Fused Alumina can¡¯t burst¡¢pulverise and craze in the using course.
