Ductile iron is an iron-carbon casting material whose matrix includes carbon in the form of nodular graphite particles. Rounded graphite nodules in the ductile iron matrix offer greater resistance to stress concentration when compared to graphite flakes (as in gray cast iron) and, therefore, inhibit the creation of cracks.
