Silicon carbide grinding wheels are generally recommended for resurfacing aluminum, while silicon carbide or aluminum oxide (or a mixture of both) work well on cast iron. Aluminum oxide is usually required for grinding steel (such as diesel crankshafts, racing crankshafts and steel flywheels), while CBN (cubic boron nitride or “Borazon”) works best on cast iron parts.
