Usage

Black corundum is mainly used in free grinding, such as the underside polishing of metal parts before electroplating, aluminum products, suitable for bicycle, motorcycle, sewing machine, watch parts, lighting, plastic and hardware tools polishing, also suitable for sandblasting (rust removal, glass spray), processing materials, manufacturing resin cutting pieces, Angle grinding pieces and coated abrasive tools.  Black corundum grit sand and micropowder are especially suitable for grinding and polishing of stainless steel workpiece and manufacturing of whetstone and grinding paste.  Black corundum segment sand is the preferred material for anti-skid pavement and underground coal mine storage.
