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.Product DescripitionWhite Fused Alumina for sandblastingWhite fused alumina for sandblasting abrasive is processed by high quality corundum as raw material andutilized by unique advanced technology. It is characterized by short grinding time, high efficiency, goodreturns ,low price and so on. In particular, its advantages such as high hardness, big specific gravity, goodchemical stability and unique self-sharpening ,it becomes the first choice for the sandblasting technics,meanwhile, it is also the ideal material for sandblasting and derusting, workpiece cleaning, and polishing.White Fused Alumina For Precision CastingWhite fused alumina is the high grade refractory raw material, main crystal system isα- Al2O3, white color.It is characterized by high volume density, low apparent porosity, stable volume and thermal stabilityperformance and so on, it is can be used for shell making material of heavy steel casting, especially the alloycasting, core sand, coating material and melt film precision casting, and it is also can be used as half precisionblasting and precision blasting material for hardened steel, alloy steel and so on.White Fused Alumina for abrasiveThis kind of white fused alumina electrically fused in arc furnace with high grade processed alumina as rawmaterial. It has higher hardness and slight lower toughness comparing with brown fused alumina. It is alsocharacterized by its high purity, ability of self-sharpening, better cutting, less heat emit, higher efficiency,acid and alkali resistance, good thermal stability. As the abrasive materials, it is suitable for grinding high-speed, high carbon steel, as loose grains, it widely used for bonded and coated abrasives ,polishing,precision casting and so on.White Fused Alumina for refractoryComparing with brown fused alumina. It is also characterized by its high purity, acid and alkali resistance,good thermal stability. It's the high grade refractory materials.Products SpecificationPurposeSpecificationChemical Composition(%)Magnetic material content(%)maxAbrasives gradeAl2O3minFe2O3maxSiO2maxTiO2maxgrain12-80990.050.260.080.002390-150990.060.280.090.0021180-220990.080.300.100.0018micropowder240-400098.50.10.400.15-Refractory gradeGroup Size0-1mm1-3mm3-5mm5-8mm990.10.350.3-Fine Powder-180mesh-200mesh-240mesh-320mesh990.10.350.3-colorwhite Hardness(mohs)9.0Melting point(°C)2250Maximum service temperature(°C)1900Ture density(g/cm3)3.9Abrasives gradeGrain: 16#,20#,24#30#,36#,46#,54#,60#,80#,100#,120#,150#,180#,220#Micropowder:240#,280#,320#,360#,400#,500#,600#,800#,1000#,1200#,1500# 2000#,2500#,3000#,4000#Refractory grade1-0mm,3-1mm,5-3mm,5-8mm -200mesh,-240mesh,-320meshApplication it are suitable for grinding high-speed,high carbon steel high-grade refractory materials abrasives tool grinding and polishing ceramics LED sandblasting aviationPackaging &Delivery1.25kg woven bag,40 woven bags/jumbo bag.2.25kg woven bag,40 woven bags/pallet3.25kg paper bag,40 paper bags/pallet4.25kg paper bag,40 paper bags/paper boxFAQ:Q: Are you factory?A: Yes, SEPPE is acomprehensive industrial Manufacturer Group.
