Description

Brown aluminimu oxide Brown aluminium oxide is fused in an electrical furnace by high temperature. Its main raw materials are bauxite, anthracite. It display brown. Its chemical composition contains Al2O3, a small amount of SiO2, TiO2, and Fe2O3, etc. The microhardness is ********0kg/mm2. The toughness is higher than silicon carbide. Abrasive articles made of it are suited for grinding metals of highten sile strength such as steel, annealed malleableiron and hard high-class refractory products. The degree of refractory is up to ***0 degree. Abrasives:F*2, F*4, F*6, F*0, F*2, F*4, F*0, F*6, F*0, F*6, F*4, F*0, F*0, F*0, F*0, F**0, F**0, F**0, F**0, F**0, F**0 Refractory:**1mm, **3mm, **5mm, **8mm etc
