White Fused Alumina Sand Abrasives For Refractory

Introduction White fused alumina/White aluminium oxide (WA)is electrically fused in the furnace with high grade processed alumina as raw material..It has high purity,ability of self-sharpening,better cutting,less heat emit,higher efficiency,acid and alkali resistance,good thermal stability.Abrasives tools made of it are suitable for grinding high-speed,high carbon steel ,etc.It also can be used as grinding and polishing,precision casting,spaying and coating, medium body for chemical industry,special ceramics and high-grade refractory materials, etc. Quick Details Type Index WFA Grit Fine Powder guarantee  value typical value guarantee  value typical  value Chemical  composition(%) Al2O3 ≥99 99.24 ≥99 99.12 SiO2 ≤0.2 0.12 ≤0.3 0.19 Fe2O3 ≤0.1 0.04 ≤0.15 0.08 Na2O ≤0.35 0.3 ≤0.45 0.33 Actual Density(g/cm3) ≥3.9 Bulk Density(g/cm3) 1.75-1.95 Mons’ hardness 9.0 Grit Size(mm) 8-5mm, 5-3mm, 3-1mm, 0-1mm 320mesh-0, 280mesh-0, 240mesh-0, 200mesh-0, 180mesh-0 ( Other special specifications could be supplied as required ) Fine Power(mesh) F230 F240 F280F320 F360 F400F500 F600F800 F1000 F1200 F1500 F2000 ( Other special specifications could be supplied as required )     Packaging & Delivery Packaging Details: 25kg PVC bag+1 MT big bag Delivery Detail: 5 wroking days The application 1.
