I-Ni90Cr10 iyingxubevange ye-nickel-chromium ye-austenitic (NiCr alloy) ukuze isetshenziswe emazingeni okushisa afika ku-1200°C (2190°F). I-alloy ibonakala ngokumelana okuphezulu, ukumelana okuhle kwe-oxidation kanye nokuzinza kwefomu elihle kakhulu. Ine-ductility enhle ngemuva kokusetshenziswa kanye nokushisela okuhle kakhulu.
I-Ni90Cr10 isetshenziselwa ukushisisa izinto zikagesi ezinsizeni zasekhaya nasezithandweni zezimboni. Izinto ezisetshenziswayo ezijwayelekile ama-ayina ayisicaba, imishini yoku-ayina, izifudumezi zamanzi, ama-plastic molding dies, ama-ayina asodayo, izakhi ze-tubula ezigoqelwe ngensimbi nezinto ze-cartridge.
Ngenxa yezakhiwo ezinhle kakhulu zokunamathela ze-surface oxide, i-Ni90C10 inikeza impilo yesevisi ephakeme kakhulu uma kuqhathaniswa nama-alloys e-nickel-chromium okuncintisana.

I-CHROMEL vs ALUMEL isetshenziswa ku-oxidizing, inert noma emkhathini wokunciphisa owomile. Ukuchayeka ku-vacuum kunomkhawulo wesikhathi esifushane. Kumele ivikelwe emikhathini enesulfure kanye ne-oxidizing kancane. Ithembekile futhi inembile emazingeni okushisa aphezulu.I-Chromel: I-Chromel iyingxubevange ye-nickel elinganiselwa ku-90% kanye no-10% we-chromium. Isetshenziswa ekwenzeni ama-conductor aqondile we-ANSI Type E kanye no-Type K thermocouples, amadivaysi okulinganisa izinga lokushisa ahlanganisa amakhondaktha amabili ahlukene.
