Detailed Description

Brown aluminium oxide/brown fused alumina is fused and crystallized under high temperature from a mixture of bauxite and other and other raw materials. It is characterized by its high hardness,good toughness and shape in size. Abrasives tools made of it are suitable for grinding metals of high-tensile strength such as: carbon steel,general-purpose alloy steel,annealed malleable iron and hard broze,etc.It also can be used as refractory materials. Abrasives grade Grit 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 The physical and chemical analysis Al2O3 MIN 95% TiO2 MAX 3.0% Fe2O3 MAX .3% SiO2 MAX 1.5% Crystal sys tem Hexagonal Color Brown Micro hardness HV1800-2200 Grinding ability(compared with diamond as one) 0.10 Hardness(mohs) 9 Ture density 3.9 g/cm3 Bulk density 1.68-1.95g/cm3 Purpose Specification Chemical Composition(%) Magnetic material content(%)max Abrasives grade Al2O3min Fe2O3max SiO2max TiO2max grain 12-80 95 0.3 1.5 3.0 0.05 90-150 94 0.3 1.5 3.0 0.03 180-220 93 0.3 1.5 3.5 0.02 micropowder 240-4000 92.5 0.5 1.8 4.0 — Refractory grade Group Size 0-1mm 1-3mm 3-5mm 5-8mm 94.5 0.3 1.5 3.0 — Fine Powder -180mesh -200mesh -240mesh -320mesh 93.5 0.5 1.5 3.5 — color Dark brown Hardness(mohs) 9.0 Melting point(℃) 2250 Maximum service temperature(℃) 1900 Ture density(g/cm3) 3.9 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.LED 7.sandblasting 8.aviation
