Abrasives manufacturers Black aluminum oxide (BA) abrasive media is easy to pour and ideal for removing rust. The abrasive blast media can be used with blast cabinets and pressurized blasters for sandblasting and cleaning applications. From blasting clean surfaces for repainting to cleaning rust and grime off tools and equipment, this aluminum oxide abrasive gets the job done. Black corundum is often used for sandblasting, grinding and polishing surface treatment of various stainless steel, ordinary steel, bamboo wood, glass and other workpieces, especially for grinding and polishing of stainless steel and other workpieces. Its grains of F14-F80 are often used for sandblasting to remove rust and impurities on the surface of the workpiece, it has moderate hardness and good toughness, it is used for sandblasting and descaling of steam turbine blades with high efficiency, which can achieve thorough descaling without damage Effect of Turbine Blade Performance; Its grains of F80-F320 are bonded to the cloth wheel to grind and polish the workpiece, or it can be made into a fiber polishing wheel for polishing; Its sands of F320-F1000 are often used to make polishing wax, resin grinding blocks and other abrasive tools to finely polish the workpiece. Black fused alumina is mixed together with other abrasives with high hardness and good wear resistance, which can be used to make resin grinding wheels, resin cutting discs, resin grinding discs, ultra-thin discs and other resin abrasives, coated abrasives.
