Vaega:
Faʻatasi ai ma le umi o le auaunaga. Faʻamafanafanaina vave. maualuga le faʻaogaina 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 e puipuia ai le siosiomaga. Ma se isi mea i le uaea nichrome taugata. E mafai ona faʻapipiʻiina e tusa ai ma manaʻoga o tagata faʻatau
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.
Vaega o talosaga
O a matou oloa e faʻaaogaina lautele i masini togafitiga vevela, vaega taʻavale, uʻamea ma uʻamea gaosiga,
alamanuia alumini, meafaigaluega metallurgical, petrochemical meafaigaluega, tioata masini, sima masini,
masini taumafa, masini tau vailaau, ma alamanuia inisinia eletise.
