Black Fused Alumina Oxide, HS Code 2818109000, CAS No.1302-74-5, also known as low-alumina oxide corundum, is a type of abrasive material that is commonly used in various industrial applications. It is made from the high-quality bauxite ore by fusing it in an electric arc furnace at high temperatures. During this process, the aluminum oxide content in the bauxite is reduced, resulting in a material that is predominantly composed of aluminum oxide and iron oxide.
Black Fused Alumina Oxide Features
*Abrasive Properties: It is an abrasive material with excellent cutting and grinding properties. It is used in applications, such as sandblasting, grinding wheels, abrasive belts, and abrasive powders.
*Strength and Durability: It has good strength and durability, making it a reliable choice for applications where wear resistance is essential.
*Chemical Composition: Black fused alumina oxide typically contains aluminum oxide (Al2O3) as the primary component, along with iron oxide (Fe2O3) and small amounts of other impurities.
