Diamond Strength Brown Fused Alumina

Diamong Strength Brown Fused Alumina: Specification: high hardness High toughness Resistance of high-temperature Anti-oxidation Corrosion resistance Our company owns a bauxite mine, a smelting factory and a processing factory, and we are a professional BFA manufacturer including mining, smelting, processing, inspection, selling and transportation. Now we have two 3150KVA tilting pouring electrical arc fuenaces, the annual output reached 30,000 tons for brown fused alumina. Brown Fused Alumina is made by high-quality bauxite as main material, fusing and purifying in a pouring electric arc furnace at a temperature of over 2200°c, and made into different grain size through crystal, choosing, crashing, magnetic, separating, screening, washing and acid cleaning, etc. Chemical composition: Technical specificationBFA97BFA95SiO2<0.8<1.2Al2O3>97>95Fe2O3<0.3<0.3TiO2<2.0<3.0Na2O<0.2<0.2CaO+ MgO<0.8<0.8Humidity<0.2<0.2Magnetic Iron<0.1<0.1Specific Gravity3.85gr./cm33.85gr./cm3
