Product Description

 

         

           Black fused alumina is a new type of black, dark gray solid particles. Black corundum, also known as low-alumina corundum, is a gray-black crystal that is produced by smelting bauxite in an electric arc furnace and has a main phase of α-Al2O3 and iron spinel, characterized by low Al2O3 content. And there is a certain amount of Fe2O3 (about 10%), which has the characteristics of moderate hard bottom, high toughness, high temperature resistance, and stable thermal properties.

 

 

 

       

            Black fused alumina is mainly used for polishing and sandblasting of stainless steel, metal products, optical glass, bamboo and wood products. It is also a novel abrasive for manufacturing resin grinding wheels, cutting blades and gauze. The black corundum abrasives are basically concentrated, with strong cutting force, high toughness, hardness and softness, good wear resistance, and high work efficiency. It is ideal for grinding, polishing and sandblasting stainless steel products.
