Black Silicon Carbide is produced in electrical resistance furnaces from high purity silica sand and petroleum coke. Its combination of being very hard and sharp makes it a very aggressive abrasive ideal for coated abrasive applications.
Coated Abrasive materials can be used for the polishing, finishing or stock removal from wood, metal, ceramics, plastics, rubber, stone and other materials.
