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 loo yaqaan 'NI80cr20 waa korontokalkaalinta kuleylkas appiances guriga, foornooyinka warshadaha iyo iska caabinta (adysiund-ka (saboolka birta, mashiinnada birta, kuleylka biyaha, caloosha balaastigga ahi waxay dhintaan, birta caleenta tuubbooyinka tuubbada tuubbada iyo walxaha babushku.
