Mitundu yosiyanasiyana ya ma aloyi apamwamba a Copper & low Nickel okhala ndi kukana kwakukulu kapena kocheperako ndizodziwika pakutsika kwa kutentha kokwanira. Pokhala ndi kukana kwambiri kwa okosijeni ndi dzimbiri zamankhwala, ma aloyiwa amagwiritsidwa ntchito poletsa mabala olondola mawaya, ma potentiometer, zida zowongolera voliyumu, ma rheostats olemetsa amakampani komanso kukana kwamagetsi amagetsi. Zosiyanasiyana zimagwiritsidwa ntchito potenthetsera zingwe zokhala ndi ma conductor otsika komanso ngati ma chubu mu "zowotcherera zamagetsi". Copper Manganese alloy imagwiritsidwa ntchito ngati zinthu zokhazikika pakulondola, zokhazikika komanso zopinga.
