Magnesium treatment is a required step within the production of ductile (DI) iron and compacted (CGI) iron.

The primary purpose of introducing magnesium to the molten metal is the formation of spherical graphite, also called spheroids or nodules (DI) and compacted graphite (CGI) respectively. These graphite forms, when produced correctly, are essential to provide the iron with the desired mechanical properties.
