What makes Ductile Iron…“Ductile Iron?”

Both ductile iron and cast iron have graphite within. If you look closely (with a high-power microscope with 100x magnification or more) at regular cast iron (gray iron), you will see the graphite bits look like squiggly lines called “flakes.”  When you look at the graphite in ductile cast iron, however, they look like little spheres or nodules (thus the spheroidal graphite iron and nodular iron names).

We give Keith Millis credit for creating ductile iron way back in 1943.  He and his buddies Albert Gagnebin and Norman Pilling received US patent 2,485,760 and US Patent 2,485,761 for making ductile iron using magnesium (Mg) in the metallurgy (the metal composition or what was in the secret recipe) to get the graphite to line up into spheres.

Millis was not the first to strengthen normal cast iron.  We still cast Meehanite® castings today.  Augustus Meehan patented the Meehanite process back in January of 1931.  Meehan used calcium silicide to also produce similar nodules to what is in ductile iron.

Yet it is ductile iron that has become one of the most popular types of iron casting. Development of ductile iron continued into the 1950s, making the process of ductile iron casting better leading to acceptance of ductile iron, acceptance proven out by the nine-fold increase in use during the 1960s as an engineered material for commercial applications.
