BFA brown sandblasting material
Product description for BFA brown sandblasting material:
Brown sandblasting material BFA is made of high quality bauxite, anthracite and iron scrap by high temperature melting in electric arc. Its texture is dense, high hardness, brown, toughness, particle form ball, suitable for the manufacture of ceramic, resin high consolidation grinding tools and grinding, polishing, refractory material, sandblasting, precision casting.
Brown sandblasting material BFA is made of bauxite/anthracite coal, and smelted in electric-arc furnace of high temperature more than 2000 degrees. Abrasives tools made by Brown sandblasting material BFA are suitable for metal with high tensile(like: steel, malleable iron, bronze etc). Suitable for product high consolidation abrasive, and suitable for grinding, polishing, blasting, precision casting etc. brown fused alumina is also used for refractory material. Brown sandblasting material BFA with characteristics like: high purity, good crystalline liquidity, low coefficient of linear expansion, corrosion resistance, high temperature, high strength.
