Fa'atasi ai ma le umi o le tautua ola. Fa'avevela vave. maualuga le fa'aogaina o le vevela. Temperature uniformity. E mafai ona fa'aoga tu'usa'o. Pe a faʻaaogaina i le voltage faʻatatau, e leai se mea faʻafefe. O se uaea faʻavevela eletise puipuia o le siosiomaga. Ma se isi mea i le uaea nichrome taugata. E mafai ona faʻapipiʻiina e tusa ai ma manaoga o tagata faatau

FeCrAl alloys o loʻo faʻaalia i le sili ona lelei o le faʻamaʻiina o le faʻamaʻi ma le faʻamautuina lelei o foliga e mafua ai le umi o le ola elemene.

E masani ona faʻaaogaina i elemene faʻavevela eletise i totonu o ogaumu fale gaosimea ma meafale.

Fe-Cr-Al u'amea ma maualuga resistivity ma auaunaga vevela nai lo lena mo NiCr alloy ma e maualalo foi tau.

Uamea-chrome-aluminium fa'agata eletise fa'amalo e fa'aaoga lautele mo le fa'atūina o elemene fa'avevela eletise i meafale ma ogaumu fale gaosi oloa. O fa'aoga masani o u'amea mafolafola, masini auli, fa'avevela vai, pa'u fa'apalapala palasitika, u'amea fa'apipi'i, mea fa'apipi'i fa'apipi'i u'amea ma elemene kalama.

O a matou oloa e faʻaaogaina lautele i masini togafitiga vevela, vaega taʻavale, uʻamea ma uʻamea gaosiga,

alamanuia alumini, meafaigaluega metallurgical, petrochemical masini, tioata masini, sima masini,

masini taumafa, masini tau vailaau, ma alamanuia inisinia eletise.
