Black Silicon Carbide – Bonded Abrasives and General Industrial (including Pressure Blasting)
Download: Technical Data Sheet | Material Safety SheetDescription:
Black Silicon Carbide is produced in electrical internal 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 many applications.
Applications:
Black SiC is typically used on hard or brittle materials. It is also used for kiln furniture, lapping and polishing, non-woven, tumbling, pressure blasting, anti-skid, electrical heating elements, aerospace, composites, etc.
