BFA Brown alumina for coated abrasives BFA Brown alumina for coated abrasives is made of bauxite/anthracite coal,and smelted in electric-arc furnace of high temperature more than 2000degrees.BFA Brown alumina for coated abrasives is suitable for metal with high tensile like: steel, malleable iron,bronze etc).and suitable for grinding, polishing, blasting, precision casting etc.BFA Brown alumina for coated abrasives is also used for refractory material. Brown alumina abrasive with characteristics like: high purity, good crystalline liquidity, low coefficient of linear expansion, corrosion resistance, high temperature, high strength. Applications of BFA Brown alumina for coated abrasives: 1.sand blasting for aluminum profile/copper material/glass/washed jeans/precise mould 2.grinding for konescope/glass/monocrystalline silicon/lens/jadeware 3.abrasion-proof material for expressway/airstrip/dock/parking lot/stadium 4.bonded abrasives and coated abrasives 5.surface preparation and finishing 6.Thermal Spraying(Plasma Spraying) 7.Super Refractories,Ceramics and Tiles 8.Lapping & Micro-blasting applications
