Ni80Cr20 is nickel-chromium alloy (NiCr alloy) inoratidzwa nepamusoro resistivity, yakanaka oxidation kuramba uye yakanaka kwazvo fomu kugadzikana. Yakakodzera kushandiswa patembiricha inosvika 1200 ° C, uye inobata hupenyu hwesevhisi hwepamusoro kana ichienzaniswa neIron chromium alumium alloys.
Yakajairika mashandisirwo eNi80Cr20 magetsi ekudziya zvinhu mumidziyo yemumba, maindasitiri emoto uye resistors (waya mawondo resistors, simbi firimu resistors), simbi dzakatsetseka, michina yekuayina, hita dzemvura, kuumbwa kwepurasitiki kunofa, simbi dzekutengesa, simbi sheathed tubular zvinhu uye cartridge zvinhu.
