Black aluminium oxide (Lower Aluminium Oxide Abrasive) is a new kind of abrasive fused from aluminum oxide material for applications such as polishing of stainless steel and non-ferrous metals, optical glass, bamboo and 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 can reduce heat generated during grinding.
