With the support of our expert, our company is dedicated Exporter of Black Corundum in Gongyi, Henan, China.
Black corundum performance characteristics
Black corundum sand hardness is moderate, the toughness is bigger wear-resisting sharp edges and corners, the sharpness is strong, grinding is less calorific value, high pure degree of polishing machining, the polishing performance much higher than other similar products at home and abroad, the aluminum content is greater than 82% black corundum, high hardness and great toughness and flexibility, wear-resisting and durable;The caking property and good hydrophilicity, facilitate the mill;When grinding block less, less heat, workpiece will not burn;Since the sharpness is strong, high efficiency, no scratches, and processing, cast high finish;More than double higher than that of brown fused alumina polishing ability, finish improve 2 above.

Black corundum purposes
Black corundum abrasives suitable for stainless steel, aluminum, metal plating before floor polishing and sanding, polishing and 2.5 times higher than that of other abrasive efficiency, bright and clean degree increased by 1.5 times.At present, the most widely used in stainless steel kitchen utensils and appliances, lighting lamps and lanterns of motorcycle parts, auto parts and other medium hardness materials fine polishing, also used in grinding of freedom.
