I-80/20 NI i-with ye-wir i-wiar yi-alloy esetyenziswe kubushushu osebenza ukuya kuthi ga kwi-1200 ° C (2200 ° F). Ukwenziwa kwayo kweekhemikhali kunika ukunganyangeki kakuhle kwe-oxidation, ngakumbi phantsi kweemeko zokutshintsha rhoqo okanye ukugcwala kobushushu ngokubanzi. Oku kwenza ukuba kube lula kwizicelo ezahlukeneyo kubandakanya izinto zokufudumeza kwizixhobo zasekhaya kunye nezamashishini, abaphathi beenxeba-zenxeba, ukuya kwishishini le-aerospace.
