Brown Fused Alumina is also called as brown aluminum oxide,it selects the high quality bauxite as main material,then fused in arc furnace under high temperature,finally screened into different sizes.Brown Fused Alumina(BFA) is divided into Tilting Furnace BFA,Fixed Furnace BFA according to the smelt . types of arc furnace;It is also divided into Barmac BFA,Roller BFA,Ball Milling BFA according to the different crushing types;

Why brown fused alumina F46#,F60#,F80 is suitable for blasting stainless steel parts?
First grade Brown fused alumina contains 95% Min Al2O3,9 mohs hardness,its high hardness and high strength can remove the oxide scale, impurities easily and achieve one certain roughness.The fine grit of brown fused alumina used in blasting process, the lower toughness will be achieved,meanwhile,it will improve the surface's cleanliness.
BFA 46# coaser grit has higher hardness and larger particle size,while BFA 80# finer grit has more tiny particle size and lower hardness,so BFAF46#,F60#,F80# is more popularg grit size for blasting stainless ,steel parts,since blasting media requires BFA in higher hardness and angular shape.
