Masini fetaui lelei

Masini faʻatulagaina uʻamea o uamea mea ma faʻapitoa tino meatotino (pei o maneta, eletise, ma vevela meatotino). O le tele o faʻaupuga faʻatumuina o loʻo faʻavae i luga o uʻamea, ma naʻo ni nai faʻavae i luga o metala e le o ni ferrous. Masani aofia ai maneta alloys (vaʻai maneta mea), ofuvae faʻapipiʻi, faʻalauteleina alloys, vevela bimetals, eletise alloys, hydrogen teuina faʻaputuga (vaʻai hydrogen teuina mea), foliga manatua alloys, magnetostrictive alloys (vaʻai magnetostrrupt mea), etc. 

Vaevaeina fetaui lelei alloys i 7 vaega e tusa ma o latou eseese tino meatotino, pei o: vaivai maneta alloys, deformed tumau maneta alloys, eletise alloys, faʻalauteleina alloys, vevela bimetals, tetee alloys, ma thermoelectric alloys.
