Black Silicon Carbide is a high-hardness, high-brittleness abrasive designed for hard and brittle materials. It is the preferred, or even the only, choice for hard and brittle non-metallic materials such as glass, ceramics, granite, and marble. Its self-sharpening properties ensure consistent and efficient cutting. It is an extremely cost-effective option, providing excellent results and lower costs when the extreme purity of green silicon carbide is not required.
