Black fused alumina is a black color artficial corundum for abrasives. It's made of fusion of bauxite and reducing agent in electric arc furnace. Black fused aluminium Oxide has certain content of ferro oxide and silicon oxide, which make it looks black. Black fused aluminium oxide has 9 mohs hardness. Black fused alumina has good features as strong tenacity, better bonding ability, giving less heat, good self-sharpening, smooth surface and high finish. Black alumina is suitable for polishing various spare parts such as, bicycles, machines, hard metal tools, medical apparatus, glass products and stone grinding. Black alumina also the right material for making abrasive tools: fiber- reinforced cutting wheels, grinding wheels, sand cloth, paper and polishing compounds It is used in production processes such as. Black fused alumina; It does not contain respirable free silica (SiO2).Our company's expert technical team will be happy to assist you.
Application Areas;
Black fused alumina is an essential component used in production of bonded abrasives (grinding wheels) and coated abrasives (sandpaper), refractories, industrial floors. Black 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.
