Zusammenfassung:	The present invention is directed to an alloy composition, a method of making it and a method of treating molten cast iron with such alloy to produce ductile and compacted graphite cast iorns. The alloy may contain from 0.1 % to 10% silicon, from 0.05 to 2.0% cerium and/or other rare earth elements, from 0.5 to 4% magnesium, 0.5 to 6.5% carbon (percent by weight) the balance being iron.
