... Compacted graphite (CG) irons are the newest member of the cast iron family. Compacted graphite irons have inadvertently been produced in the past as a result of insufficient magnesium or cerium levels in melts intended to produce ductile (spheroidal or nodular graphite) iron; however, it has only been...

..., and the development of malleable iron was a significant breakthrough. Ductile iron was discovered in 1948 and offered casting capability for thicker sections compared with malleable iron. This development was a low-cost alternative for steel forgings and castings. Compacted graphite iron, developed in 1976...
