When mg added to graphite cast iron, it forms nodules instead of flakes. The element mg added to promote Spheroidizing react with the solute in the liquid to form heterogeneous nucleation sites.

Nodular cast iron, spheroidal graphite iron, spherulitic graphite cast iron is a type of cast iron, most commonly magnesium (note magnesium boils at 1100°C and iron melts at 1500°C) and, less often now, cerium (usually in the form of Mischmetal).
Tellurium has also been used. Yttrium, often a component of Misch metal, has also been studied as a possible Nodulizer.
