Ductile iron cast, nke bu nnochite anya igwe nkedo, ana akpo ya nodular iron. Nodular cast iron na-enweta graphite nodular site na spheroidization na inoculation ọgwụgwọ, nke na-eme ka usoro ihe eji arụ ọrụ nke ọma.nkedo akụkụ, karịsịa plasticity na ike, ka inweta ike dị elu karịa carbon carbon.
Iron ductile abụghị otu ihe mana ọ bụ akụkụ nke otu ngwongwo nke enwere ike imepụta iji nwee ọtụtụ njirimara site na njikwa microstructure. Uzo a na-achoputa na otu nke ihe bu udi nke graphite. Na ígwè ductile, graphite dị n'ụdị nodules karịa flakes dị ka ọ dị na ígwè isi awọ. Thedị nkọ nke flakes nke graphite na-eme ka isi ihe nrụgide dị n'ime matriksị ọla ahụ na ụdị nke nodules dị obere karịa, si otú a na-egbochi okike nke mgbawa ma na-enyekwa ikike dị mma nke na-enye alloy aha ya.
