Vinthu vya alloy ivyo vikugwiriskirika nchito comene pa iron cast cast iron .

Vinthu vya alloy ivyo vikusazgikirapo chisulo cha mtundu wa grey vingagaŵika pafupifupi mu vigaŵa vinayi, ndiko kuti, vinthu vya graphitization, vinthu vyakupangiska carburizing, vigaŵa vyakukhazikika vya mikanda na vinthu vyakunozga.
Mu ndondomeko ya kukhozgeka kwa chisulo, carbon, silikoni, aluminiyamu, sulfure, mkuwa na vinthu vya nickel vili na ntchito yakukhozgera kupanga graphite, iyo yingawoneka kuti ni vinthu vyakupangika na graphitized. Kweni, nkhongono ya vinthu vikupambana chomene, mwachiyelezgero, mkuwa uli pafupifupi 20% ya silicon. Nickel na mkuwa nawo ŵali na maudindo ghaŵiri: kukhozgera graphitization pa nyengo ya kusintha kwa cocrystal; kukanizga graphitization pa nyengo ya kusintha kwa cocrystal, iyo yikovwira kupanga mikanda yiwemi chomene, ntheura yingawonekaso kuti ni chinthu chakukhazikika.
Ivyo vikuchitika chifukwa cha titanium navyo ni vyakusuzga. Kuyowoya mwakudumura, titanium ni chinthu chakukhora chomene icho chikupanga chinthu, kweni para ivyo vili mukati mwake ni vichoko chomene (mwachiyelezgero, .<0.08%), its fine compounds can be used as the core of graphite, has the role of promoting graphitization.
Tin, antimony, manganese, molybdenum, chromium, varomium na niobium vyose vingatondeska vula na kukura kwa graphite, kukhozga chizgoŵi cha kupanga carburns, ndipo vyose vya carburns vyakukhazikika. Kukhuŵara kwa molybdume kukukhwaskana na unandi wake wakusazgikira. Molybdenum ivyo vili mu chisulo,<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.
