Black Aluminum Oxide for Surface Cleaning Of Stainless Steel

Product Detail

Black Fused Alumina has good features as high hardness, strong tenacity, better bonding ability, giving less heat, good self-sharpening, smooth surface and high finish. Black Alumina is suitable for polishing various spare parts such as, stainless steel cookware, bicycles, sewing-machine, hard metal tools, medical apparatus, glass products and stone grinding. Black Alumina also the right material for making abrasive tools: fiber- reinforced cutting wheels, grinding wheels, sand cloth, paper and paste.




Applications 

1. Abrasive tools 

2. Refractory material 

3. Lapping, polishing, non-shid tiles, and pressure blasting when a high purity and highly friable abrasive is needed.
