Cupronickel CuNi44 mkuwa-nickel aloyi kukana waya ndi sing'anga-otsika resistivity
Copper-nickel resistance alloy, yomwe imadziwikanso kuti constantan, imadziwika ndi kukana kwamagetsi kwambiri komanso kutentha pang'ono kwa kukana. Aloyiyi imawonetsanso mphamvu zolimba kwambiri komanso kukana dzimbiri. Itha kugwiritsidwa ntchito pa kutentha mpaka 600 ° C mumlengalenga.
CuNi44 ndi aloyi yamkuwa-nickel (CuNi alloy) yokhala ndising'anga-otsika resistivityzogwiritsidwa ntchito pa kutentha mpaka 400°C (750°F).
CuNi44 nthawi zambiri imagwiritsidwa ntchito pazinthu monga zingwe zotentha, ma fuse, ma shunts, resistors ndi mitundu yosiyanasiyana ya owongolera.
