Silicon carbide is a commonly used material for sandblasting nozzles because it exhibits good erosion and abrasive resistance. It is both impact resistant and durable like tungsten carbide nozzles, but lighter. A Clemlite® silicon-carbide-lined nozzle may last approximately 500 hours when using expendable abrasives.
Walnut shell blasting grit is an excellent replacement for sand (free silica) to avoid inhalation health concerns. Walnut shells are recommended for use on soft surfaces such as aluminum, brass, wood, fiberglass and other surfaces where no pitting is desired. Walnut shells will leave a smooth, dull finish.

Black silicon carbide ( Carborundum) is generally used for the abrasive wheel, slurry, refractory and ceramic industries. Silicon Carbide is special in the way it breaks down. As it breaks down into smaller particles, the media will expose new, sharp edges. Therefore, black silicon carbide can be best used over and over, such as in a rock tumbler.
