Black silicon carbide, also known as black silicon carbide, black silicon carbide, the hardness of the corundum class of abrasives, cutting edge Ruifeng, brittle. Good thermal conductivity, heat quickly, since the sharp performance is better than corundum abrasives. Applicable to the manufacturing of ceramic, resin, rubber wheel, refractory; gray cast iron, white cast iron, bronze, brass, minerals, aggregates, glass, leather, rubber, plastic and heat-sensitive material grinding. Black silicon carbide abrasive for sandblasting, dry grinding, free grinding and jewelry, jade, agate products, cutting and shaping.
