Product Details
Brown Fused Alumina For Refractory
|
Brown Fused Alumina is also known as Brown Fused Aluminum Oxide or BFA. With a Mohs hardness of 9, Brown Fused Aluminum Oxide is a high strength, wear-resistant material possessing a strong ability to resist vigorous chemical attacks (such as acid and alkali) at extreme temperatures. BFA can be melted in electric-arc furnace of very high temperature above 2000℃ which has a low iron content making it particularly valuable in refractory applications.
