Description

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℃. Brown fused alumina *5% Abrasives:F**-F**0 Refractory:**1mm, **3mm, **5mm, **8mm etc. Powder:**0F, **0F, **0F, **5F etc. Brown fused alumina *8% Refractory:**1mm, **3mm, **5mm, **8mm etc. Powder:**0F, **0F, **0F, **5F etc.
