Detailed Description

White fused alumina/White aluminium oxide (WA)is electrically fused in the furnace with high grade bayer 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 materialsfor grinding and polishing,precision casting,spaying and coating, medium body for chemical industry,special ceramics and high-grade refractory materials,etc. The physical and chemical analysis Al2O3 MIN 99.53% Na2O MAX 0.4% Fe2O3 MAX 0.1% SiO2 MAX 0.1% Crystal system Hexagonal Color White Micro Hardness HV2200-2300 Grinding ability(compared with diamond as one) 0.12 Hardness(mohs) 9 Ture density 3.9 g/cm3 Bulk density 1.75-1.95 g/cm3 Purpose Specification Chemical Composition(%) Magnetic material content(%)max Abrasives grade Al2O3min Fe2O3max SiO2max TiO2max grain 12-80 99 0.05 0.26 0.08 0.0023 90-150 99 0.06 0.28 0.09 0.0021 180-220 99 0.08 0.30 0.10 0.0018 micropowder 240-4000 98.5 0.1 0.40 0.15 — Refractory grade Group Size 0-1mm 1-3mm 3-5mm 5-8mm 99 0.1 0.35 0.3 — Fine Powder -180mesh -200mesh -240mesh -320mesh 99 0.1 0.35 0.3 — color white Hardness(mohs) 9.0 Melting point(°C) 2250 Maximum service temperature(°C) 1900 Ture density(g/cm3) 3.9 Abrasives grade Grain: 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 grade 1-0mm,3-1mm,5-3mm,5-8mm -200mesh,-240mesh,-320mesh Application 1. it are suitable for grinding high-speed,high carbon steel 2. high-grade refractory materials 3. abrasives tool 4. grinding and polishing 5. ceramics 6.
