Fa'amatalaga Lautele
FeCrAl u'amea e faia i le maualuga-vevela, ferritic u'amea-chromium-aluminium alloy lea e mafai ona fa'aoga i le vevela e o'o atu i le 1350tikeri. O talosaga masani mo le 0Cr21Al6Nb e pei o elemene faʻavevela eletise i totonu o ogaumu vevela maualuga i le vevela vevela, keramika, tioata, sila, ma mea tau eletise.
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. A faʻaaogaina i le fua faʻatatau, e leai se mea faʻafefe. O se puipuiga o le siosiomagauaea faamafanafana eletise. Ma se isi mea i le taugatauaea nichrome.E mafai ona faʻapitoa 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.
Talosaga
0Cr21Al6 Uamea-chrome-aluminium fa'a'ese'ese fa'amalo eletise e fa'aaoga lautele mo le faia o elemene fa'avevela eletise i meaafale 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.
nofoaga 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.
