Silicon Carbide Grit is the hardest blasting media available. This high-quality product is manufactured as a hard, blocky, angular grain shape.
Apraksts
Description
Black silicon carbide is made from quartz sand and smokeless acetylene as the main raw material. It is made via light resistance from hydro metallurgical, it is black opaque body hexagonal crystal and MOHS-hardness the 9.15, which is after diamond and boron carbide with crisp and sharp performance and certain degree of conductive heat.
Black silicon carbide is higher toughness than green silicon carbide with sic purity 98%, it have been used for processing glass, ceramic, stone, refractory materials, cast iron and other metal.
