Constantan Physical Properties

Copper nickel alloy constantan silig, kaas oo leh adkaysi koronto oo hooseeya, kulaylka u adkaysta iyo daxalka u adkaysta, fudud in la farsameeyo iyo alxanka rasaasta. Waxa loo isticmaalaa in lagu sameeyo qaybaha muhiimka ah ee gudbinta culayska xad-dhaafka ah ee kulaylka, jabiyaha kulaylka caabbinta hooseeya, iyo qalabka korantada. Sidoo kale waa shay muhiim u ah fiilada kuleylka korontada. Waxay la mid tahay nooca ' cupronickel'.
