E masani ona aofia ai mea faʻamaneta (vaʻai mea faʻamaneta), faʻamau faʻamaʻi, faʻalautelega faʻamalo, bimetal vevela, faʻamalo eletise, faʻapipiʻi faʻapipiʻi hydrogen (silasila mea e teu ai le hydrogen), faʻasologa o mea e manatua ai, faʻamau faʻamaneta (vaʻai mea magnetostrictive), ma isi.
E le gata i lea, o nisi o mea fou e masani ona aofia ai i le vaega o mea faʻapipiʻi saʻo i faʻaoga faʻapitoa, e pei o le faʻaitiitia o le faʻaitiitia o le vibration, mea faʻafefete (vaʻai mea faʻamalosi), faʻamau faʻamaufaʻailoga maneta, faʻamaufaʻailoga superconducting, uʻamea amorphous microcrystalline, ma isi.
Ua vaevaeina alloys sa'o i ni vaega se fitu e tusa ai ma o latou meatotino faaletino eseese, e pei: alloys mageta vaivai, deformed alloys mageta tumau, alloys elastic, alloys faalauteleina, bimetal thermal, alloys tetee, ma alloys tulimanu thermoelectric.
O le tele o u'amea sa'o e fa'avae i u'amea u'amea, na'o ni nai mea e fa'avae i u'amea e le o ni u'amea.
O mea fa'amaneta e aofia ai fa'amama maneta vaivai ma fa'amau maneta malo (fa'aigoa fo'i o fa'amau maneta).O le mea muamua e maualalo le malosi fa'amalosi (m), a'o le malosi fa'amalosi malosi (> 104A/m).E masani ona faʻaaogaina o uʻamea mama alamanuia, uʻamea eletise, uʻamea-nikeli uʻamea, uʻamea-alumini uʻamea, alnico uʻamea, seasea lalolagi cobalt alloy, ma isi.
Thermal bimetal o se mea tu'ufa'atasia e lua pe sili atu fo'i fa'apala o u'amea po'o u'amea fa'atasi ma fa'aopoopoga fa'aopoopo e fa'apipi'i mau le tasi i le isi i luga o le fa'afeso'ota'iga atoa.O loʻo faʻaaogaina le uʻamea maualuga-faʻalauteleina e pei o le vaega galue, o le faʻaogaina o le paʻu maualalo e faʻaaogaina e pei o le passive layer, ma e mafai ona faʻapipiʻi se interlayer i le ogatotonu.A'o suia le vevela, o le bimetal vevela e mafai ona punou, ma fa'aaogaina e gaosia ai fa'ameamea, va'a ta'avale, mea e amata ai mea a le fale, ma alavai e pulea ai le vai ma le kesi mo le gaosiga o vaila'au ma le eletise.
Alu eletise e aofia ai le sa'o sa'o fa'a'au'au, fa'aeletonika eletise, thermocouple mea ma mea fa'afeso'ota'i eletise, ma isi, ma e fa'aaogaina lautele i le fanua o masini eletise, meafaifa'aili ma mita.
Magnetostrictive alloys o se vasega o mea uʻamea faʻatasi ma aʻafiaga magnetostrictive.E masani ona faʻaaogaina o uʻamea faʻavae uʻamea ma nickel-based alloys, lea e faʻaaogaina e gaosia ai le ultrasonic ma lalo o le vai transducers acoustic, oscillators, faamama ma masini.
1. Pe a filifilia se auala saʻo smelting uʻamea, e manaʻomia le faʻavasegaina o le lelei, tau o le ogaumu, ma isi, i le tele o tulaga.E pei o le manaʻomia o le ultra-low carbon saʻo le pulea o mea, faʻamalo, faʻaleleia le mama, ma isi. O se auala lelei e faʻaoga ai le ogaumu eletise eletise faʻatasi ai ma le faʻamamaina i fafo o le ogaumu.I lalo o le faʻavae o manaʻoga maualuga, o le ogaumu faʻapipiʻi gaogao o se auala lelei.Ae ui i lea, o le gafatia tele e tatau ona faʻaaogaina i le tele e mafai ai.
2. E tatau ona gauai atu i le sasaa o tekinolosi e puipuia ai le faaleagaina o le uamea uʻamea i le taimi o le sasaa, ma le sasaa faʻasolosolo faʻasolosolo e iai lona taua tulaga ese mo alloys saʻo.
