Black aluminium oxide
1. 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.It 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, timepieces, 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.
