Ductile Iron is an alloy of Iron, Carbon and Silicon, also known as Spheroidal Graphite Iron or Nodular Cast Iron. The process of manufacturing Ductile Iron involves adding magnesium to low-sulfur molten iron. Due to the reaction with magnesium, the excess carbon (graphite) present in the iron forms as multiple small nodules and the resultant product is known as Ductile Iron.Ductile Iron is preferred to Cast Iron because while it retains the corrosion resistance of Cast Iron, it has more than double the tensile strength [Cast Iron- 180 MPa (min), Ductile Iron – 420 MPa (min)].
Cast Iron is brittle because the graphite is present in plate-like flakes. On the contrary, in Ductile Iron, the shape of the graphite becomes a spheroidal nodule, which offers better mechanical properties and makes Ductile Iron sturdy, structurally stronger and shock-proof.
