Ni90Cr10 is an austenitic nickel-chromium alloy (NiCr alloy) inoshandiswa patembiricha inosvika 1200°C (2190°F). Iyo alloy inoratidzirwa nepamusoro resistivity, yakanaka oxidation kuramba uye yakanaka kwazvo fomu kugadzikana. Iyo ine yakanaka ductility mushure mekushandisa uye yakanakisa weldability.
Ni90Cr10 inoshandiswa kumagetsi ekudziya zvinhu mumidziyo yemumba nemavira emaindasitiri. Mashandisirwo akajairika simbi dzakatsetseka, michina yekuayina, hita dzemvura, kuumbwa kwepurasitiki kunofa, simbi dzekutengesa, simbi sheathed tubular zvinhu uye cartridge zvinhu.
Nekuda kwekunyanya kunaka kwekunamatira zvimiro zvepasi oxide, Ni90C10 inopa hupenyu hwepamusoro sevhisi kana ichienzaniswa nemakwikwi nickel-chromium alloys.

CHROMEL vs ALUMEL inoshandiswa mukuita oxidizing, inert kana yakaoma kuderedza mamiriro ekunze. Kuratidzwa kune vacuum kunogumira kunguva pfupi. Inofanirwa kuchengetedzwa kubva kune sulfurous uye marginally oxidizing atmospheres. Kuvimbika uye kwakarurama pakupisa kwakanyanya.Chromel: Chromel ialloy yeinofungidzirwa 90% nickel uye 10% chromium. Inoshandiswa pakugadzira maconductor akanaka eANSI Type E uye Type K thermocouples, midziyo yekuyera tembiricha ine maviri akasiyana makondukita.
