What is fused alumina abrasives?
Fused alumina abrasives is artificial abrasives with Al2o3 as its main content.It includes white fused alumina abrasive,brown fused alumina abrasive and pink fused alumina abrasive and so on.Because fused alumina abrasives have advantages of high hardness,good wear resistance and good cutting ability,it is used widely in various industries.Of course,different fused alumina abrasive has its own features and used for different fields.
White fused alumina abrasives
White fused alumina abrasive is made from high purity aluminum oxide via smelt under high temperature.It appears white powder,with Al2O3 more than 99.4% and Mohs hardness 9.0.White fused alumina abrasives is suitable for grinding aluminum alloy, stainless steel,metal etc
Brown fused alumina abrasives
Brown fused alumina abrasive is also caleed brown aluminum oxide,brown emery sand ,brown corundum etc,made mainly from bauxite.It appears brown powder,main chemical is Al2O3 too,which is about 95%.Brown fused alumina has lower hardness than white corundum,but has better toughness.Besides,brown fused alumina costs lower and it mainly is used for grinding and polishing normal metal etc.
Pink fused alumina abrasives
Pink fused alumina abrasives looks pink,very beautiful.It contains Al2O3 more than 98% and Cr2O3 0.2-2%.Because it posseses high strength,toughness and bulk density,the abrasive tools made from it has better cutting ability.
Besides, there are black fused alumina abrasives,zirconia fused alumina abrasives,single crystal fused alumina abrasives,ceramic fused alumina abrasives etc
In a summary,fused alumina abrasives are playing an important role is industrial production because of its perfect physical properties and chemical.
