Description
Black Silicon Carbide #46 Grit is a high-quality abrasive material produced from petroleum coke and silica sand through high-temperature electric resistance furnace smelting, followed by crushing, shaping, and accurate particle classification.
Featuring high hardness, excellent friability, and sharp cutting edges, Black Silicon Carbide #46 Grit delivers fast cutting performance and consistent abrasive results. Its relatively fine particle size provides a good balance between material removal efficiency and surface finish quality, making it suitable for applications where controlled cutting and uniform processing are required.
Compared with #40 Black Silicon Carbide Grit, #46 Black Silicon Carbide offers a finer and more refined grain structure, enabling smoother surface treatment and improved processing accuracy while maintaining strong abrasive efficiency. It is commonly used in abrasive blasting, metal surface preparation, grinding wheels, coated abrasives, refractory materials, ceramics, stone processing, and other industrial applications.
With stable physical properties and reliable performance, Black Silicon Carbide #46 Grit is an ideal choice for manufacturers seeking durable and efficient silicon carbide abrasive solutions for medium-fine grinding and surface finishing processes.
