Product Description

Brown Fused Alumina

Product Description

Feature
BFA has good crystallization, well toughness, low linear expansion coefficient, corrosion resistance.
Details information
Brown Fused Alumina is produced by the smelting of Calcined Bauxite in
an electric arc furnace at temperatures greater than 2000C.
Application: Wear-resistant and refractory products, Reusable abrasive,
Resin bond abrasive tools, Grinding and polishing media, Ceramic
grinding wheels, sandblasting, precision casting.
Application
Brown fused alumina is an essential component used in production of bonded abrasives (grinding wheels) and coated abrasives (sandpaper), refractories, industrial floors. Brown fused alumina is reusable in compressed air blasting. It is a pure and very hard abrasive. Aluminium oxide is used to anchor pattern creation prior to coating or bonding, rust, scale removal, sweeping, matte surface finish of steel, stainless steel, aluminum, non-ferrous metals, glass, stone and other surfaces.

Brown fused alumina; also known as electro corundum, corundum, and aluminum oxide, is obtained as a mineral while fusing bauxite in an electric arc furnace. Its main component is alumina Al2O3. Brown fused alumina is an ecologically clean and extremely hard material. Brown fused aluminum oxide; Used in abrasive, refractory production and in dry and wet blasting applications where it is reusable. Brown fused alumina is used over and over again because of its sharp and self-regenerating edges. Brown fused alumina; It does not contain respirable free silica (SiO2). Our company's expert technical team will be happy to assist you.
