Alloy simbi iboka re alloy iro rinonyanya kubatanidza iron, kabhoni uye zvimwe zvakasanganiswa zvinhu zvakaita seSi, Mg, Cr, Mo, Ni, Mn, Cu etc. Cast alloy simbi inogona kupatsanurwa kuita cast low low alloy simbi (iyo yakazara alloy zvinhu. ishoma pane kana kuenzana ne5%), simbi yakakandwa (iyo yakazara alloy zvinhu i5% kusvika 10%) uye yakakandwa yakakwira alloy simbi (iyo yakazara alloy zvinhu zvakakura kupfuura kana kuenzana ne10%). Zvichienderana neakasiyana mashandisirwo uye chimiro, alloy simbi inogona kukandwa nemhando dzakawanda dzekukanda maitiro anosanganisira kukanda mari, kukanda jecha, kukanda ganda, kurasika furo kukanda uye vacuum casting. Thealloy simbi castingskazhinji iine mamwe akasiyana emagetsi emhando senge kupisa kupisa, kupfeka kuramba, stainless uye corrosion resistance.
