High Al2O3 purity 99.2% white alumina oxide blasting media  White alumina oxide blasting media , is made from high quality alumina by being melted above 2000°C in the electric arc furnace. It is characterized by high purity, great self-sharpening, acid and alkali resistance, high temperature resistance and stable thermal performance. Its hardness is a little higher than brown fused alumina.White alumina oxide blasting media is with low toughness, great grinding ability, small heat and high efficiency.White alumina oxide blasting media can be made into all kinds of abrasives, suitable for grinding high carbon steel, high speed steel, stainless steel and other fine-grained abrasives; it can be also used for precision casting and high-refractory materials.    The physical and chemical analysis: Model:8#-220# Chemical compositions Physical properties Items Value of specification(%) Items property Al2O3 99min Color White SiO2 0.1max Bulk density 1.95g/cm3 NaO2 0.4max True density 3.95g/cm3 Fe2O3 0.1max Hardness Morse hardness 9 Micro hardness 21600-22600kg/mm3 Usage Sandblasting material Content of magnetic substance 0.0023%max   Our Advantages: 1).one-stop service 2).supply abrasives since 1999 3).A grade products with high purity 4).production capacity:1000-1500 metric ton/month   Package: 1).if no special request, we will use normal packing,25kg PVC bag, then 40 bags in a big bag for 1000 Kilograms. 2).if need special packing or marks, please list them in your E-mail.
