                      Application:
                      Brown Aluminum Oxide, also known as corundum, are made of high-quality bauxite, carbon materials and iron scraps through high-temperature smelting and crushing in the electric furnace. The main component of brown corundum is alumina, which can be divided into several grades according to the different aluminum content. Brown corundum has the advantages of high temperature resistance, corrosion resistance and strength. At present, it is widely used in the production of abrasive Abrasives, sandblasting and polishing of workpiece castings, refractories, etc.
                      Brown corundum abrasive is not powdered, does not burst, and has great toughness. It is mainly used for smelting precious metals, special alloys, making high-quality ceramics, making blast furnace lining, automobile spark plug, building heat-resistant and anti-oxidation coating, etc. At the same time, brown corundum can also be used as thermal insulation materials. The corundum light brick, corundum fiber products, corundum hollow ball and other products made of brown corundum abrasive can be used for thermal insulation on the walls and roofs of various high-temperature furnaces.
                      Brown corundum abrasives also have the advantages of high hardness, excellent wear resistance and high strength, which can be used to make high-strength reaction vessels and pipes, as well as for grinding and polishing of mechanical parts, making of cutting tools, abrasives, bulletproof materials, etc.
