Product Description

BFA brown fused allumina refractory material

$BFA brown fused alumina refractory material$

BFA, also calleded Brown Fused Aluminum Oxide,Brown Aluminum Oxide or Brown Corundum(Korund)named by its brown color, is artificial electro fused corundum with 95% Aluminum Oxide. 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.

BFA Characters

Refractory/Fireproof
BFA 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
BFA a very tough material with 9 grade mosh hardness
Sharp Grain
BFA is a crystal material with sharp edges and ideal for durable grinding, polishing and abrasives.
High Density
BFA is a dense material with high bulk density and true gravity. It is used as a material in casting and water purifying processes.
