Description
Black Silicon Carbide #180 Grit is a fine-grade silicon carbide abrasive material manufactured from high-purity petroleum coke and silica sand through high-temperature electric furnace smelting, crushing, and precision particle classification processes.
With high hardness, sharp abrasive edges, and excellent grain consistency, Black Silicon Carbide #180 Grit provides controlled cutting performance and superior surface refinement. Its fine particle size enables accurate material removal while reducing surface imperfections, making it suitable for applications requiring smooth finishes and precise processing control.
Compared with #150 Black Silicon Carbide Grit, #180 Black Silicon Carbide Grit features a finer grain structure and improved particle uniformity, allowing smoother grinding results and enhanced surface quality. It is widely used in precision grinding, polishing preparation, coated abrasives, bonded abrasive tools, ceramic processing, stone finishing, refractory materials, and other industrial applications.
Due to its excellent abrasive stability, thermal resistance, and reliable performance, Black Silicon Carbide #180 Grit is an ideal choice for manufacturers seeking high-quality abrasives for fine grinding and precision surface treatment.
