Ductile cast iron is a type of cast iron known for its impact and fatigue resistance, elongation, and wear resistance due to the spherical (round) graphite structures in the metal. Ductile cast iron is also called ductile cast iron, spheroidal graphite cast iron, or nodular cast iron. Ductile cast iron castings are very strong compared to regular cast iron (gray iron). The tensile strength of cast iron is 20,000 - 60,000 psi while ductile cast iron starts at 60,000 psi and can go to 120,000 psi. The yield strength for ductile cast iron is generally 40,000 - 90,000 psi but the yield strength of cast iron is so low it is considered not measurable. Ductile cast iron is great for use where you need strong metal with wear resistance. Here is a sample list of things made from or contain ductile cast iron : Pipe and pipe fittings, Axles, Connecting rods (like in engines), Crankshafts, Cylinders, Disc brake calipers, Gears and Gear Boxes, etc.
