Brown fused alumina is fused and crystallized under high temparaturefrom a mixture of bauxite and other raw materials.It is brown andfeatures high hardness and toughness.The Abrasives tools made of it aresuitable for gringing metals of high-tensile strength such as carbonsteel, general-purpose alloy steel,malleable cast iron and hard bronze,etc. It also can be used as refractory materals,chemicaladditives,precision founding and anti-sliding materials.
