Premium Black Corundum Abrasives 36# 16# for Versatile Applications

Product Description

Weixiang Black Fused Alumina :

Black corundum is a new type of polishing materials, with high quality bauxite as main raw materials, less add reducing agent, and then, in the Canon of high temperature smelting electric arc furnace, color is black. Black corundum sand hardness is moderate, the toughness is bigger wear-resisting sharp edges and corners, the sharpness is strong, less calorific value when grinding, polishing machining workpieces cleaning degree is high, the polishing performance much higher than other similar products at home and abroad, the aluminum content is greater than 82% black corundum, high hardness and great toughness and flexibility, wear-resisting and durable; The caking property and good hydrophilicity, facilitate the mill; When grinding block less, less heat, workpiece will not burn; Since the sharpness is strong, high efficiency, no scratches, and processing, cast high finish;
