                   black fused alumina for polishing and abrasive

Black aluminium oxide abrasive (Lower Aluminium Oxide Abrasive) is a new abrasive fused from aluminum oxide material for applications such as polishing of stainless steel and non-ferrous metals. Common applications are grinding and polishing of stainless steel, optical glass, bamboo or other materials. The black mineral has aluminum oxide's high hardness, adheres well to common bonding materials, and is tough but friable enough to cut well and reduce heat generated during grinding. Uses for black aluminum oxide are grinding wheels, powder for wire cutting and slicing and coated abrasives. Can be used in grinding
