Saina fa'atau oloa nichrome 90 Ni90
Ni90Cr10 o se austenitic nickel-chromium alloy (NiCr alloy) mo le faʻaaogaina i le vevela e oʻo atu i le 1200°C (2190°F). O le uʻamea o loʻo faʻaalia i le maualuga o le resistivity, lelei le faʻamaʻiina o le faʻamaʻiina ma le mautu lelei. E i ai le ductility lelei pe a uma ona faʻaaogaina ma lelei lelei weldability.
Ni90Cr10 e faʻaaogaina mo elemene faʻavevela eletise i mea faʻaoga fale ma ogaumu fale gaosi oloa. O fa'aoga masani o u'amea mafolafola, masini auli, fa'avevela vai, fa'apalapala palasitika pa'u, u'amea fa'amau, mea fa'apipi'i u'amea u'amea ma elemene kalama.
Ona o mea faʻapipiʻi sili ona lelei o le oxide i luga, o le Ni90C10 e ofoina atu le ola tautua sili atu pe a faʻatusatusa i le faʻatauvaʻa nickel-chromium alloys.

CHROMEL vs ALUMEL o loʻo faʻaaogaina i le faʻamaʻiina, faʻamago poʻo le faʻamamago faʻaititia o le ea. Fa'aalia ile vacuum fa'atapula'a ile taimi pupuu. E tatau ona puipuia mai le sulfurous ma fa'ama'i fa'ama'i fa'ama'i. Fa'atuatuaina ma sa'o i le maualuga o le vevela.Chromel: O le Chromel o se fa'afefiloi o le 90% nickel ma le 10% chromium. E faʻaaogaina i luga o le fausiaina o taʻavale lelei o ANSI Type E ma Type K thermocouple, masini mo le fuaina o le vevela e aofia ai taʻavale eseese e lua.
