General Introduction

Copper Nickel Alloys(Cupro-nickel)

Principally destined for the manufacturing of low temperatures electric resistances so as heating cables, shunts, resistances for automobile, they have a maximum operating temperature of 752 degrees Fahrenheit.
They do not therefore intervene in the field of resistances for industrial furnaces.

Those are alloys of chemical composition copper + nickel with addition of manganese with a low resistivity (from 231.5 to 23.6 Ohm. Mm2/ft).

The most known, CuNi 44 (also called Constantan) presents the advantage of a very low temperature coefficient.


Advantages:


Very good resistance to corrosion
Very good malleability
Very good solderability
