Black aluminum oxide supplied by our principles, which has good features as high hardness, strong tenacity, better bonding ability and hydrophilicity, giving less heat, good self sharpening, smooth surface and high finish. It's suitable for polishing various spare parts such as, bicycles, sewing machine, hard metal tools, medical apparatus, time pieces, glass products and stone grinding. It's also the right material for making abrasive tools: fiber-reinforced cutting wheels, grinding wheels, sand cloth paper and paste.
