Brown fused alumina is based on bauxite, coke as the main raw material, then melting in the electric furnace with high temperature.The abrasive tools that made of brown fused alumina is suitable for grinding high tensile metal,like general steel,malleable cast iron, hard bronze, etc.,also can be used in making high grade refractory . Brown fused alumina is charactized with high purity,good crystallization,strong liquidity,lower linear expansion rate and erosion resistance. Application: 1.It is used to make high grade refractory ,castable, firebrick etc. 2.Sand blasting--moderate hardness, high packing density, no free silica, large density, good toughness, it is the ideal "environmental protection" type sandblasting materials. 3.Free grinding.It is general domestic high grade abrasive material that is used in the field of  image tube, optical glass, monocrystalline silicon, lens, glass, crystal glass, jade, etc., 4.Resin grinder 5.Coated abrasives--It is t...
