Brown Fused Alumina is fused and crystallized under high temperature from a mixture of bauxite and other raw materials. It is brown and feature is high hardness and toughness. The 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,chemical additives,precision founding and anti-sliding materials.
