Copper Nickel Alloys
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.
Their advantages are the following:
Very good resistance to corrosion
Very good malleability
Very good solderability
