康銅的(de)電(dian)(dian)(dian)(dian)(dian)阻(zu)率比錳銅略高，電(dian)(dian)(dian)(dian)(dian)阻(zu)-溫(wen)度曲線呈線性(xing)關系。具有良好的(de)抗氧化(hua)能(neng)力及加工性(xing)。由于有較高的(de)對銅熱(re)電(dian)(dian)(dian)(dian)(dian)動(dong)勢，因此該合(he)金僅限于制作(zuo)交流(liu)用的(de)精密電(dian)(dian)(dian)(dian)(dian)阻(zu)，滑(hua)動(dong)電(dian)(dian)(dian)(dian)(dian)阻(zu)，啟動(dong)、調節變(bian)阻(zu)器(qi)及200°C以(yi)下使用的(de)電(dian)(dian)(dian)(dian)(dian)阻(zu)應(ying)變(bian)計，也可作(zuo)為100°C以(yi)下低溫(wen)電(dian)(dian)(dian)(dian)(dian)加熱(re)元件(jian)。
