Ductile cast iron ke mofuta oa thepa e entsoeng ka tšepe e matla e phahameng e entsoeng lilemong tsa bo-1950.Ts'ebetso ea eona e akaretsang e haufi le tšepe.E itšetlehile ka ts'ebetso ea eona e babatsehang eo e 'nileng ea sebelisoa ka katleho bakeng sa ho lahla likarolo tse ling ka matla a rarahaneng, matla a phahameng, ho tiea le ho hanyetsa ho apara.Litšepe tsa ductile li fetohile ka potlako ho ba thepa ea tšepe ea tšepe e sebelisoang haholo ea bobeli ho feta ea tšepe e bohlooho.Seo ho thoeng ke "tšepe ho e-na le tšepe", haholo-holo e bua ka tšepe ea ductile.

Ducular iron ke graphite e chitja ka kalafo ea spherulation le ea ho ima, e ntlafatsang ka katleho thepa ea tšepe e entsoeng ka tšepe, haholo-holo polasetiki le ho tiea, e le ho fumana matla a phahameng ho feta tšepe ea carbon.

Cast iron e na le carbon content e fetang 2.11% ea tšepe ea carbon alloy, ka tšepe ea kolobe ea indasteri, tšepe ea tšepe le lisebelisoa tsa eona tsa alloy ka mor'a hore mocheso o phahameng o qhibilihe le ho etsoa, ​​​​ho phaella ho Fe, carbon le tse ling tse entsoeng ka tšepe ka mokhoa oa graphite, haeba ho na ha graphite strip ea tšepe ea tšepe e bitsoang grey cast iron kapa grey cast iron, worm cast iron called worm inki iron, sehlopha sa tšepe e entsoeng ka tšepe e bitsoang white cast iron or code iron, le spherical cast iron e bitsoa spherical enke cast iron.

The lik'hemik'hale tsa ductile tšepe ntle le tšepe hangata: carbon content 3.0 ~ 4.0%, silicon content 1.8 ~ 3.2%, manganese, phosphorus, sebabole kakaretso se feteng 3.0% le palo e loketseng ea seoelo lefatše, magnesium le likarolo tse ling globtized.
