Brown Fused Alumina (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
Brown Fused Alumina 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.
