Black Corundum

Black corundum abrasive is made of high quality bauxite as the main raw material, less reducing agent, high temperature smelting by electric arc furnace, the color is black. Moderate hardness, its toughness wear-resistant edge sharp, self-sharpening good, less heat when grinding, polishing and processing of workpiece cleanliness, black corundum abrasive basic material concentration is high, cutting force, good toughness, rigid and flexible, wear-resistant, high efficiency. Black corundum abrasive, suitable for stainless steel, metal products plating before the bottom surface polishing and sandblasting, also suitable for glass, bamboo, wood, stone and other products grinding and polishing. Black corundum is widely used in tableware polishing industry, bottom surface polishing industry before plating, metal surface treatment industry, glass products industry, aluminum products and stainless steel polishing. It is also a new type of concentrated material for the manufacture of resin grinding wheels and abrasive cloth. At present, it is most widely used in fine polishing of stainless steel table and kitchen utensils, lamps, motorcycle parts, automobile parts and other medium hardness materials.
Black corundum is a kind of gray-black crystal with a-AL2O3 and spinel iron as the main mineral phases produced by melting bauxite in an electric arc furnace, which has the performance characteristics of high toughness, high temperature resistance, and thermal too stability. 

Abrasive composition of the basic grain concentration, cutting force, good wear resistance, high efficiency. It is mainly used for polishing and sandblasting of metal products, optical glass, bamboo and wood products, and is a novel abrasive for manufacturing resin grinding wheels, cutting discs and abrasive cloths. Polishing with this product is 2.5 times more efficient than other abrasives, and the finish is 1.5 times higher, especially the effect of grinding and polishing stainless steel products is better. Black corundum abrasive is packed in export color carton and novel plastic woven bag, weighing 25kg each.
It is used for free grinding, such as the rough grinding of the polisher before plating of products, mainly used for polishing and sandblasting of stainless steel, metal products, optical glass, bamboo and wood products, and it is also the novel abrasive for manufacturing resin grinding wheels, cutting blades and gauze. Our black corundum black corundum abrasive basic grain concentration, cutting force, toughness, rigid and flexible, good wear resistance, high efficiency. It is the most ideal product for grinding and polishing, sandblasting stainless steel products.
