I-80/20 NI CR Ukumelana ne-alloy esetshenziswa emazingeni okushisa okusebenza kuze kube ngu-1200 ° C (2200 ° F). Ukwakheka kwalo kwamakhemikhali kunikeza ukumelana okuhle kwe-oxidation, ikakhulukazi ngaphansi kwezimo zokushintsha okushintshashintsha njalo noma ukuguquguquka kwezinga lokushisa. Lokhu kwenza kube kuhle ngezinhlobonhlobo zezicelo ezibandakanya izinto zokushisa ezintweni ezisetshenziselwa izimboni nezimboni, ukumelana namanxeba e-wire, kuye embonini ye-aerospace.
