Chitsulo cha ductile ndi chabwino kwa zida za valve, chifukwa chimakhala ndi zabwino zambiri.Monga cholowa m'malo mwa chitsulo, chitsulo cha ductile chinapangidwa mu 1949. Mpweya wa carbon wa zitsulo zotayidwa ndi zosakwana 0.3%, pamene zitsulo zachitsulo ndi zitsulo zosachepera ndi 3%.Mpweya wochepa wa carbon zitsulo zotayidwa umapangitsa carbon yomwe ilipo ngati graphite yaulere osati kupanga ma flakes.Mawonekedwe achilengedwe a carbon mu chitsulo choponyedwa ndi ma graphite flakes aulere.Mu chitsulo cha ductile, graphite ndi mawonekedwe a tinthu tinatake tozungulira m'malo mwa flakes monga chitsulo chonyezimira.Poyerekeza ndi chitsulo chosungunuka ndi chitsulo choponyedwa, chitsulo cha ductile chimakhala ndi mawonekedwe abwinoko.Ndizitsulo zozungulira zomwe zimalepheretsa kupanga ming'alu, motero zimapereka ductility yowonjezera yomwe imapatsa alloy dzina lake.Komabe, flake mu chitsulo chotayidwa kumabweretsa kusowa ductility chitsulo.Ductility yabwino kwambiri imatha kupezeka ndi matrix a ferrite.

Poyerekeza ndi chitsulo choponyedwa, chitsulo cha ductile chili ndi zabwino zonse pakulimba.Mphamvu yachitsulo yachitsulo ndi 60k, pamene chitsulo chosungunuka ndi 31k chabe.Mphamvu zokolola za chitsulo cha ductile ndi 40k, koma chitsulo chosungunuka sichisonyeza mphamvu zokolola ndipo chidzasweka potsiriza.

Mphamvu ya chitsulo cha ductile imafanana ndi chitsulo chosungunuka.Chitsulo chachitsulo chimakhala ndi mphamvu zokolola zambiri.Mphamvu yotsika kwambiri ya chitsulo cha ductile ndi 40k, pamene mphamvu zokolola za zitsulo zotayidwa ndi 36k zokha.M'magawo ambiri am'matauni, monga madzi, madzi amchere, nthunzi, kukana kwa corrosion ndi kukana kwa oxidation kwa chitsulo cha ductile ndizopambana kuposa zachitsulo.Chitsulo chachitsulo chimatchedwanso chitsulo cha spheroidal graphite.Chifukwa cha mawonekedwe a spheroidal graphite microstructure, chitsulo cha ductile chimakhala chapamwamba kuposa chitsulo chosungunula mu kugwedezeka konyowa, kotero kumathandiza kuchepetsa kupsinjika maganizo.Chifukwa chofunikira chosankha chitsulo cha ductile monga zida za valve ndikuti zimakhala ndi mtengo wotsika kuposa zitsulo zotayidwa.Kutsika mtengo kwachitsulo cha ductile kumapangitsa kuti nkhaniyi ikhale yotchuka kwambiri.Kupatula apo, kusankha chitsulo cha ductile kungachepetse mtengo wamakina.
