Embonini ye-metallurgy ne-Foundry, izinsimbi ezingenayo insimbi yizinsimbi noma ama-alloys angenayo i-iron (i-ferrite) ngamanani abizayo. Uma kuqhathaniswa nensimbi eyinsimbi, izinsimbi ezingenayo insimbi zinezinzuzo eziningi zesisindo esiphansi (isbi-aluminium), conductivity ephakeme (isbithusi), impahla engeyona enozibuthe noma ukumelana nokugqwala (isbzinc). Izinsimbi ezingenayo insimbi ezisetshenziswa kakhulu ekubunjweni zihlanganisa i-aluminium, ithusi, i-nickel, i-chrome, i-molybdenum, i-manganese, i-magnesium ne-zinc, nama-alloys afana nethusi. Izinsimbi ezingenayo insimbi ngokuvamile zicwengwa nge-electrolysis. Eziningi zensimbi ezingenayo insimbi zengezwa ensimbi ngaphambi kokuthululelwa kwensimbi ukuze kutholwe insimbi ye-alloy noma insimbi ekhethekile ephonswayo enemisebenzi ethile efiselekayo njengokumelana nokugqoka, ukumelana nokugqwala, ukumelana nokushisa ... njll.
