Alloyed iron—This classifiion includes gray irons, ductile irons and white irons that have more than 3% alloying elements (nickel, chromium, molybde num, silicon or copper). Malleable irons are not heavily alloyed because many of the alloying elements interfere with the graphiteforming process that occurs dur ing heat treatment.
