Sand Blasting Black Fused Alumina

Black fused alumina is a new type of black, dark gray solid particles. It's 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.It is mostly used for free grinding, such as grinding and rough grinding before electroplating, mainly used for polishing and sandblasting stainless steel, metal products, optical glass ,bamboo and wood products, and is also a novel abrasive for manufacturing resin grinding wheels, cutting pieces and emery cloth.
