Introduction to Brown Corundum
Brown corundum, also known as brown fused alumina, is one of the most widely used abrasives in the world. It is produced by fusing high - grade bauxite in an electric arc furnace at extremely high temperatures. The resulting product is a tough, sharp, and durable abrasive material with excellent cutting and grinding performance.
Brown corundum has a series of outstanding properties. It has high hardness, good toughness, and strong self - sharpening ability. These characteristics make it suitable for a wide range of applications, including grinding, sandblasting, polishing, and surface treatment of metals, ceramics, glass, and other materials. In the manufacturing industry, it is used to produce grinding wheels, sandpaper, abrasive belts, and other abrasive tools. In the field of surface treatment, it can effectively remove rust, scale, and old paint from the surface of workpieces, improving the surface quality and adhesion of coatings.
