Product Description
Ultrafine copper nickel microfilament CuNi23 (NC030)
Copper Nickel Alloys(Cupro-nickel)

Model No.:
CuNi1, CuNi2, CuNi6, CuNi8, CuNi10, CuNi14, CuNi19, CuNi23, CuNi30, CuNi44.

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, Cupronickel) 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
