I-Ductile cast iron luhlobo lwemathiriyeli yentsimbi eyomelele kakhulu eyaphuhliswa ngeminyaka yoo-1950.Ukusebenza kwayo okubanzi kusondele kwintsimbi.Isekelwe ekusebenzeni kwayo okugqwesileyo ukuba isetyenziswe ngempumelelo ukuphosa ezinye iindawo ngamandla anzima, amandla aphezulu, ukuqina kunye nokumelana nokunxiba.Intsimbi etyhidiweyo iphuhliswe ngokukhawuleza ibe yinto esetyenziswa ngokubanzi yentsimbi yesibini emva kwentsimbi engwevu.Into ebizwa ngokuthi "intsimbi endaweni yentsimbi", ngokuyininzi ibhekisela kwintsimbi ye-ductile.

I-iron ducular yi-spherical graphite ngokusebenzisa i-spherulation kunye nonyango lokumitha, oluphucula ngokufanelekileyo iimpawu ze-mechanical yentsimbi etyhidiweyo, ngakumbi iplastiki kunye nokuqina, ukuze ufumane amandla aphezulu kune-carbon steel.

Intsimbi yokuphosa ngumxholo wekhabhoni ongaphezulu kwe-2.11% ye-iron carbon alloy, nge-iron yehagu ye-industrial, isinyithi esilahlwayo kunye nezixhobo zayo ze-alloy emva kokunyibilika kobushushu obuphezulu kunye nokubunjwa kokubunjwa, ukongeza kwi-Fe, i-carbon kunye nenye intsimbi etyhidiweyo kwifom yegraphite, ukuba Ukuna kwentsimbi ye graphite strip yentsimbi ebizwa ngokuba yi grey cast iron okanye grey cast iron, intsimbi yombungu ebizwa ngokuba yintsimbi yeinki yombungu, iqela lentsimbi ebizwa ngokuba yintsimbi etyhidiweyo emhlophe okanye intsimbi yekhowudi, kunye nentsimbi eyingqukuva ibizwa ngokuba yintsimbi eyingqukuva.

Ukubunjwa kweekhemikhali zensimbi ye-ductile ngaphandle kwentsimbi ngokuqhelekileyo: umxholo wekhabhoni 3.0 ~ 4.0%, umxholo we-silicon 1.8 ~ 3.2%, i-manganese, i-phosphorus, i-sulfure iyonke ayidluli i-3.0% kunye nenani elifanelekileyo lomhlaba onqabileyo, i-magnesium kunye nezinye izinto zeglobti.
