Ductile cast iron ndi mtundu wachitsulo champhamvu kwambiri chopangidwa mu 1950s.Ntchito yake yonse ili pafupi ndi chitsulo.Zimachokera ku ntchito yake yabwino kwambiri yomwe yakhala ikugwiritsidwa ntchito bwino poponya ziwalo zina ndi mphamvu zovuta, mphamvu zambiri, kulimba komanso kukana kuvala.Chitsulo chachitsulo chasanduka chitsulo chogwiritsidwa ntchito kwambiri chachiwiri pambuyo pa chitsulo chotuwa.Zomwe zimatchedwa "zitsulo m'malo mwachitsulo", makamaka zimatanthawuza chitsulo cha ductile.

Chitsulo cha ducular ndi graphite yozungulira kudzera mu spherulation ndi gestation chithandizo, chomwe chimapangitsa kuti mawotchi apangidwe achitsulo, makamaka pulasitiki ndi kulimba kwake, kuti apeze mphamvu zapamwamba kuposa carbon zitsulo.

Kutayira chitsulo ndi mpweya zili oposa 2.11% ya chitsulo mpweya aloyi, ndi mafakitale nkhumba chitsulo, zitsulo zitsulo ndi aloyi zipangizo pambuyo mkulu kutentha kusungunuka ndi kuponyera kupanga, kuwonjezera Fe, mpweya ndi chitsulo choponyedwa mu graphite mawonekedwe, ngati kugwa kwa chitsulo cha graphite chachitsulo chotchedwa chitsulo chotuwa kapena chitsulo chotuwa, chitsulo cha nyongolotsi chotchedwa nyongolotsi inki chitsulo, gulu la chitsulo chonyezimira chotchedwa white cast iron or code iron, ndi chitsulo chowulungika amatchedwa chitsulo chozungulira inki.

The mankhwala zikuchokera ductile chitsulo kupatula chitsulo zambiri: mpweya zili 3.0 ~ 4.0%, pakachitsulo okhutira 1.8 ~ 3.2%, manganese, phosphorous, okwana sulfure osapitirira 3.0% ndi yoyenera kuchuluka kwa osowa lapansi, magnesium ndi zinthu zina globtized.
