RS-Brown Fused Alumina 95 / Alumina Oxide20081107

Brown Fused Alumina / Brown Aluminum Oxide / Brown Corundum / Corundum Maroon / BFA / A BFA: Brown fused alumina is fused and crystallized under high temperature from mixture of bauxite and other materials, characterized by its high hardness, good toughness and shape in particles. Abrasive tools made of it are suitable for grinding metals of high-tensile strength such as carbon steel, general purpose alloy steel, malleable cast-iron and hard bronze etc. It also can be used as refractory materials. Brown Fused Alumina also can be called as Brown Aluminum Oxide, Brown Corundum, Corundum Maroon, BFA, A ect. Use of Brown fused alumina: first as the refractory materials, second as the abrasive, third as the sandblasting, fourth as the precision casting ect.
