Low Resistance Copper Nickel Alloy Wire Cupronickel Metallic Colored Steel Wire
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
