High Content 85% AL2O3 Black Fused Alumina

      Black Fused Alumina 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.
