P Bag+1mt Jumbo Bag, 25kg Paper Bag+Pallet Specification: F8-F1200, P12-P2500, 0-1mm, 1-3mm,3-5mm,5-8mm, etc Origin: Zhengzhou, China HS Code: 2818109000 Product Description High Quality White Fused Alumina(WA) Sandblasting Aluminium OxideWhite fused alumina is produced by bayer alumina in an electric arc furnace at high temperatures. The product shows higher hardness and lower toughness than that of brown aluminium oxide. The materials are used to grind high carbon steel, high speed steel and chilled steel. It can also be used as polishing materials and precision founding sand, spraying and coating materials, catalyst carrier, special ceramics and super refractory materials.GrainUsagesandTypesUsageForvitrifiedwheelsFororganicwheelsForcoatedabrasivesForrefractorymaterialsTypeWAWA-BWA-PWA-RPhysicalCharacteristicsItemBasicmineralCrystalsystemCrystalcolorMohshardnessDensityWhitealuminumoxideα-Al2O3HexagonalWhite9≥3.90g/cm3ItemMicrohardnessElectricalresistivityGrindingability(comparedwithdiamondasone)Linearexpansioncoefficient(when900ºCα•10-6k-1)WhitealuminiumoxideHV2200-23001014-1016Ω•cm0.128.3ChemicalCompositionGB/T2479-2008TypeGritChemicalcomposition(%,byweight)Al2O3Na2OWAF4-F80≥99.10≤0.35F90-F150≥99.10≤0.40F180-F220≥98.60≤0.50F230-F800≥98.30≤0.60F1000-F1200≥98.10≤0.70WA-BF4-F80≥99.00≤0.50F90-F150≥99.00≤0.60F180-F220≥98.50≤0.60WA-PP12-P80≥99.10≤0.35≤0.40P100-P150≥99.10P180-P220≥98.60≤0.50P240-P800≥98.30≤0.60P1000-P1200≥98.10≤0.70P1500-P2500≥97.50≤0.90WA-R0-1mm≥99.00≤0.501-3mm≥99.00≤0.503-5mm≥99.00≤0.505-8mm≥99.00≤0.50Note:Specialrequirementsonchemicalcomposition and other termscanbesatisfiedthroughdiscussion.White Fused Alumina(WA)
