Insimbi yengxubevange iyiqembu lengxubevange ehlanganisa ngokuyinhloko insimbi, ikhabhoni nezinye izakhi eziyingxubevange ezifana neSi, Mg, Cr, Mo, Ni, Mn, Cu njll. Insimbi yengxubevange ye-Cast ingahlukaniswa ibe yinsimbi ephansi ye-alloy (ingqikithi yezakhi zengxubevange). ingaphansi noma ilingana no-5%), insimbi eyingxubevange (ingqikithi yezakhi ze-alloy ingu-5% kuya ku-10%) kanye nensimbi ephezulu ye-alloy (inani le-alloy element likhulu kune noma ukulingana no-10%). Ngokusekelwe ekusetshenzisweni okuhlukene kanye nesakhiwo, insimbi ye-alloy ingaphonswa izinhlobo eziningi zezinqubo zokuphonsa ezihlanganisa ukufakwa kwe-investimenti, ukubunjwa kwesihlabathi, ukuphonsa amagobolondo, ukukhishwa kwegwebu elilahlekile kanye nokusakazwa kwe-vacuum. Ii-alloy steel castingsngokuvamile zinezici ezithile eziyingqayizivele zemishini ezifana nokumelana nokushisa, ukumelana nokugqoka, ukumelana ne-stainless kanye nokugqwala.
