Black Silicon Carbide is a mew corundum polishing materials to model and a water-Sanshui bauxite as raw materials made by electric arc smelting temperature. The abrasives has the character of concentration, cutting ability, toughness, hardness and softness, abrasion resistance, high eficiency. It is mainly used for stainless steel,metal products, optical glass, bamboo products, polishing and sand blasting,
