Brown Fused Alumina Oxide (BFA), also calleded Brown Fused Aluminum Oxide,named by its brown color, is artificial electro fused corundum. Brown Fused Alumina is abrasion-resistant, heat-resistant with great hardness, which obtains it wide application for abrasives, refractory and blasting industries. We are professional manufacturerfor customers in different industries and countriesaccording to FEPA, JIS, GB, ISO standard. 0-1mm, 1-3, 3-5mm etc. for refractories, FEPA F sizes for bonded abrasives aluminum oxide tools, FEPA P sizes for coated abrasives aluminum oxide products We make Brown Fused Alumina micro grits F280,F320,F400,F500,F600,F800,F1000 etc for polishing and high grade abrasives. Brown Fused Alumina Oxide Characters Refractory/Fireproof Brown Fused Alumina contains 94%-97% Aluminum Oxide (Al2O3). It is an ideal raw mineral for shaped and unshaped refractory products and fireproof products, especially in steel making industry. High Strength Brown Fused Aluminais a very tough material with 9 grade mosh hardness Sharp Grain Brown Fused Alumina is a crystal material with sharp edges and ideal for durable grinding, polishing and abrasives. High Density Brown Fused Alumina is a dense material with high bulk density and true gravity. It is used as a material in casting and water purifying processes.
