white fused alumina

White aluminium oxide/white fused alumina(WA)Al2O3 99.53%...........NaO 0.3%.........Fe2O3 0.1%......... Magnetic material content 0.0023%.....color white ……hardness(mohs) 9…….ture density 3.9Marterials: aluminaWhite aluminium oxide 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.Abrasives gradeGrit size: 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
