I-Ni90Cr10 yi-austenitic nickel-chromium alloy (NiCr alloy) yokusetyenziswa kumaqondo obushushu ukuya kwi-1200 ° C (2190 ° F). I-alloy ibonakaliswe ngokumelana okuphezulu, ukuxhathisa okulungileyo kwe-oxidation kunye nokuzinza kwefom enhle kakhulu. Ine-ductility elungileyo emva kokusetyenziswa kunye ne-weldability ebalaseleyo.
I-Ni90Cr10 isetyenziselwa izinto zokufudumeza zombane kwizixhobo zasekhaya kunye neziko loshishino. Usetyenziso oluqhelekileyo zii-ayini ezisicaba, oomatshini boku-ayina, izifudumezi zamanzi, ukubumba iplastiki kuyafa, iiayini zokudambisa, izakhi zetubula ezishelwe ngesinyithi kunye nezinto zekhatriji.
Ngenxa yeempawu zokuncamathela ezilungileyo kakhulu ze-oxide yomphezulu, i-Ni90C10 ibonelela ngobomi benkonzo obuphezulu xa kuthelekiswa nokhuphiswano lwe-nickel-chromium alloys.

I-CHROMEL vs ALUMEL isetyenziselwa i-oxidizing, inert okanye i-atmosphere eyomileyo yokunciphisa. Ukuvezwa kwi vacuum kuthintelwe kumaxesha amafutshane. Kufuneka ikhuselwe kwi-atmosphere yesulfure kunye ne-oxidizing. Ithembekile kwaye ichanekile kumaqondo obushushu aphezulu.I-Chromel: I-Chromel yi-alloy eqikelelwa kwi-90% ye-nickel kunye ne-10% yechromium. Isetyenziswe ekwenziweni kwabaqhubi abalungileyo be-ANSI Uhlobo lwe-E kunye noHlobo lwe-thermocouples ye-K, izixhobo zokulinganisa ubushushu obuquka abaqhubi ababini abahlukeneyo.
