Brown Fused Alumina (BFA), also known as Brown Corundum, is a type of abrasive material made from high-quality bauxite, iron filings, and anthracite under high-temperature smelting in an electric arc furnace. After the smelting process, it undergoes crushing, grinding, and sorting to obtain particles of various sizes. This material is known for its high hardness, toughness, and resistance to wear, making it ideal for various industrial applications.
