Description

Black Silicon Carbide #120 Grit is a fine-grade silicon carbide abrasive manufactured from high-purity petroleum coke and silica sand through high-temperature electric resistance furnace smelting, followed by crushing and precision particle classification.

With exceptional hardness, sharp angular particles, and excellent wear resistance, Black Silicon Carbide #120 Grit delivers fast and consistent cutting performance while producing smooth, uniform surface finishes. Its fine particle size offers excellent process control, making it suitable for applications that require high surface quality and precise material removal.

Compared with #100 Black Silicon Carbide Grit, #120 Black Silicon Carbide Grit features a finer and more uniform particle distribution, providing improved surface smoothness and enhanced finishing performance while maintaining efficient cutting ability. It is widely used in precision grinding, surface preparation, coated abrasives, bonded abrasive tools, ceramic processing, stone finishing, refractory products, and polishing preparation.

With stable physical properties, excellent thermal stability, and reliable abrasive performance, Black Silicon Carbide #120 Grit is an ideal choice for manufacturers requiring consistent fine grinding and superior surface finishing quality.
