Silicon carbide naturally has a very sharp edged grain. The cutting material microscopically fractures as it wears, creating new razor-edged cutting faces throughout the wheel’s life. Unfortunately, silicon is not as durable as other abrasives—it’s best suited for soft metals like aluminum, iron, brass, and soft bronze.
