Description
Black Silicon Carbide #14 Grit is a coarse-grade silicon carbide abrasive material manufactured from high-purity petroleum coke and silica sand through high-temperature electric furnace smelting, crushing and precise sizing processes.
With excellent hardness, sharp cutting edges and strong abrasive performance, Black Silicon Carbide #14 Grit delivers aggressive cutting action and efficient material removal. Its relatively coarse particle size makes it ideal for heavy-duty surface preparation, abrasive blasting, grinding and applications requiring fast cutting performance.
Compared with finer silicon carbide grits, #14 Black Silicon Carbide Grit provides higher impact force and stronger stock removal capability, making it a preferred abrasive material for demanding industrial applications such as rust removal, surface cleaning, refractory processing and rough grinding.
Key Features
