Ductile iron haisi chinhu chimwe chete asi chikamu cheboka rezvinhu zvinogona kugadzirwa kuti zvive nehuwandu hwezvinhu kuburikidza nekutonga kwe microstructure. Izvo zvinowanzotsanangudza hunhu hweboka iri rezvinhu chimiro chegraphite. Mune ductile irons, iyo graphite iri muchimiro chemanodule kwete maflakes sezvairi mugrey iron. Iyo yakapinza chimiro chemaflakes e graphite inogadzira kushushikana pfungwa mukati mesimbi matrix uye yakatenderedzwa chimiro chemanodule zvishoma, nekudaro kuvharidzira kusikwa kwekutsemuka uye nekupa iyo inosimudzira ductility inopa alloy zita rayo. Kuumbwa kwemanodule kunowanikwa nekuwedzerwa kwenodulizing elements, kazhinji magnesium (noti magnesium inovira pa 1100 ° C uye iron inonyunguduka pa 1500 ° C) uye, zvishoma ikozvino, cerium (kazhinji iri muchimiro cheMischmetal). Tellurium yakashandiswa zvakare. Yttrium, kazhinji chikamu cheMisch simbi, yakadzidzwawo seinogoneka nodulizer.
