white fused alumina/abrasive

Description: white fused alumina, a kind of abrasive, was made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling. It is white with the main crystal phase alpha-Al2O3. The white alumina produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved. Usage:(1)It can make the abrasive tool to grind the great hardness material, such as the high speed steel, stainless steel and high carbon steel.(2)It also usually used for sandblasting, such as precious metal, the gold, crystal, the glass andcowboy wear.The chemical and physical analysis: Model:JIS#150 Chemical compositions Physical propertiesItemsValue of specification (%) ItemsPropertyAl2O3 99.55minColorWhiteSiO2 0.04max Bulk density1.75-1.95g/cm3Na2O 0.22max Grain density3.90g/cm3 minFe2O3 0.04maxhardnessMorse hardness9Micro hardness21600-22600kg/mm3Usagepolishing,grinding and sandblastingcontent of magnetic substance0.0023%max Mills: white fused alumina plants brown fused alumina plants black silicon carbideplants green silicon carbide plants About us: Henan Sicheng Co., Ltd, owning two manufacturing enterprises for abrasives and machinery respectively, is a comprehensive joint-stock company integrating production, R&D and trade.
