Elements za alloy ezitera okukozesebwa mu kyuma ekisuuliddwa enzirugavu .

Ebintu bya aloy ebiteekeddwa mu kyuma ekisuuliddwa enzirugavu bisobola okugabanyizibwamu ebika bina, nga bino bye bino: graphitization elements, carburizing elements, bead stabilizing elements ne elements ezirongooseddwa.
Mu nkola y’okunyweza ekyuma ekisuuliddwa, kaboni, silikoni, aluminiyamu, ekibiriiti, ekikomo n’ebintu bya niiki birina omulimu mu kutumbula okutondebwa kwa graphite, ekiyinza okutwalibwa nga elementi ezifuuliddwa grafayiti. Naye, obulungi bwa elementi bwa njawulo nnyo, okugeza, ekikomo kiri nga 20% ku silikoni. Nickel ne Copper nabyo birina emirimu ebiri: okutumbula graphitization mu kiseera ky’enkyukakyuka ya cocrystal; Okuziyiza graphitization mu kiseera ky’enkyukakyuka ya cocrystal, ekiyamba okukola obululu obutono obusingawo, kale era kisobola okutwalibwa ng’ekintu ekinywevu.
Ebiva mu titanium nabyo bizibu. Okutwalira awamu, titanium kintu kya maanyi ekikola karbide, naye ebigirimu bwe biba bitono nnyo (okugeza .<0.08%), its fine compounds can be used as the core of graphite, has the role of promoting graphitization.
Tin, antimony, manganese, molybdenum, chromium, vanadium ne niobium byonna bisobola okulemesa enkuba n’okukula kwa graphite, okutumbula omuze gw’okukola carburns, era byonna bya Carburns stable elements. Enkola ya molybdenum ekwatagana n’omuwendo gwayo ogw’okugattako. Molybdenum erimu mu kyuma ekisuuliddwa, .<0.8%, the effect of molybdenum is mild, which is to make the pearlite refinement, the content is the carburization stable element. It is generally believed that the role of manganese is to increase the amount of cast iron beads and improve the strength of cast iron. In fact, manganese is also multifaceted, when the content is high, it will make the graphite thick, thus reducing the strength of cast iron.
