The silicon carbide is a compound obtained from carbon and quartz sand combined at high temperatures (2500°C). The result is a compound which is free from iron.
It can be reused during the sandblasting process more times – which makes it a cheaper alternative than other products for sandblasting.
It has a sharp shape and the peculiarity of high hardness, only one point Mohs lower than diamond.
The features of silicon carbide make it a very aggressive abrasive for sandblasting, which can be employed to sandblast very hard materials such as tempered steels, ceramic, etc.
