Company Info
Basic Info.
Product Description
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 make Brown Fused Alumina Micro Grit for of F280-F1000 for polishing and high grade abrasives
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.
