Mewn diwydiant meteleg a ffowndri, mae metelau anfferrus yn fetelau neu aloion nad ydynt yn cynnwys symiau sylweddol o haearn (ferrite). O'i gymharu â metelau fferrus, mae gan fetelau anfferrus lawer o fanteision o bwysau isel (ee alwminiwm), dargludedd uwch (ee copr), eiddo anfagnetig neu ymwrthedd i gyrydiad (ee sinc). Mae'r metelau anfferrus a ddefnyddir fwyaf ar gyfer castiau yn cynnwys alwminiwm, copr, nicel, crôm, molybdenwm, manganîs, magnesiwm a sinc, ac aloion fel pres ac efydd.

Mae metelau anfferrus fel arfer yn cael eu mireinio trwy electrolysis. Mae llawer o'r metel anfferrus yn cael ei ychwanegu i'r haearn cyn ei arllwys i gael y dur aloi neu haearn bwrw arbennig sydd â rhai perfformiadau dymunol megis ymwrthedd gwisgo, ymwrthedd cyrydiad, gwrthsefyll gwres... ac ati.
