Ductile 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 Iron is also called ductile cast iron, spheroidal graphite cast iron, or nodular cast iron.
Ductile 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 iron starts at 60,000 psi and can go to 120,000 psi. The yield strength for ductile iron is generally 40,000 – 90,000 psi but the yield strength of cast iron is so low it is considered not measurable.
Ductile 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 iron:
Pipe and pipe fittings (almost 50% of ductile iron sold in the US is for pipe and fittings)
Connecting rods (like in engines)
Disc brake calipers
Gears and Gear Boxes
Housings and manifolds
Piano Harps (the part that holds the strings of a piano)
Suspension system parts
Valves (especially high-pressure valves)
Yokes for power transmission
