Brown fused alumina also known as electrocorundum, corundum and aluminium oxide is obtained mineralally while fusing bauxite in an electric arc furnace. Its main component is alumina Al2O3. Brown fused alumina is ecologically clean and extremely hard material. It is used in production of abrasives, refractory and in dry- and wet-blasting applications where it is reusable. Due to sharp, and self-renewable edges brown fused alumina is highly grinding. Brown fused alumina is free of not respirable crystalline silica (SiO2).
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.
