NI80CR20 waa nickel-chromium altoy (nicr alloy) oo lagu garto iska caabbinta sare, iska caabin wanaagsan, iska caabbinta muuqaalka wanaagsan iyo xasilloonida qaab aad u wanaagsan. Waxay ku habboon tahay in lagu isticmaalo heerkulka illaa 1200 ° C, oo hayso nolol adeeg ka sarreysa marka la barbar dhigo album-ka album-ka iron chromium.
Codsiyada caadiga ah ee NI80c20 waa walxaha kuleylka korantada ee aaladaha guriga, foornooyinka warshadaha iyo iska caabinta finanka, kuleylka birta, walxaha birta, walxaha tuubbooyinka ee loo yaqaan 'praft'.
