Ni80Cr20 yog ib qho hlau nickel-chromium alloy (NiCr alloy) uas muaj lub zog tiv taus siab, tiv taus oxidation zoo thiab ruaj khov zoo heev. Nws tsim nyog siv rau ntawm qhov kub txog li 1200 ° C, thiab tuav lub neej ua haujlwm zoo dua piv rau Iron chromium alumium alloys.
Cov ntawv thov ib txwm muaj rau Ni80Cr20 yog cov khoom siv hluav taws xob hauv cov khoom siv hauv tsev, cov cub tawg kev lag luam thiab cov resistors (wirewound resistors, hlau zaj duab xis resistors), cov hlau tiaj tus, cov tshuab ironing, cov cua sov dej, cov yas molding tuag, cov hlau soldering, cov hlau sheathed tubular thiab cov khoom cartridge.
