Ni80Cr20 waa nikkel-chromium alloy (NiCr alloy) oo lagu garto iska caabin sare, caabbinta oksaydhka wanaagsan iyo xasilloonida qaab aad u wanaagsan. Waxay ku habboon tahay in lagu isticmaalo heerkul ah ilaa 1200 ° C, waxayna haysaa nolol adeeg heer sare ah marka loo eego birta chromium aluminium alloys.
Codsiyada caadiga ah ee Ni80Cr20 waa korontowalxaha kululayntas ee qalabka guriga, foornooyinka warshadaha iyo iska caabiyeyaasha (iska caabinta fiilada, biraha iska caabinta filimka), birta fidsan, makiinadaha feeraha, kuleyliyaha biyaha, caagagga wax ka beddelashada ayaa dhinta, biraha alxanka, walxaha tuubada galka leh ee birta ah iyo walxaha kartoonada.
