Ni80Cr20 yog npib tsib xee-chromium alloy (NiCr alloy) uas muaj zog tiv taus, zoo oxidation kuj thiab zoo heev daim ntawv stability. Nws yog qhov tsim nyog rau kev siv ntawm qhov kub txog li 1200 ° C, thiab tuav lub neej kev pabcuam zoo dua piv rau Hlau chromium alumium alloys.
Cov ntawv thov rau Ni80Cr20 yog cov khoom siv hluav taws xob cua sov hauv cov khoom siv hauv tsev, cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob (wirewound resistors, hlau zaj duab xis resistors), tiaj tus hlau, ironing tshuab, dej rhaub dej, yas molding tuag, soldering hlau, hlau sheathed tubular ntsiab thiab cartridge ntsiab.
