Las aleación de cobre y níquel se utilizan principalmente en la fabricación de resistencias eléctricas que van a trabajar a bajas temperaturas, como pueden ser los cables de calefacción, derivaciones y resistencias para automóviles.  La temperatura máxima de funcionamiento de las diferentes aleaciones de cobre-níquel es de 400ºC. La aleación de Constantan presenta la ventaja de un coeficiente de temperatura muy bajo, gran resistencia a la corrosión, buena maleabilidad y soldabilidad.

A parte de las diferentes aleaciones de cobre níquel que podemos suministrar tanto en hilo como fleje, también disponemos de lámina de cobre y lámina de latón cortada a medida.

A continuación le indicamos algunas de las aleaciones de cobre-níquel que suministramos. En caso de estar buscando alguna otra dispone del formulario de contacto.
