    Cuprothal 294 Copper Nickel Alloy Wire 0.08mm for Precision Instrument

    Cuprothal 294 Copper Nickel Alloy Wire 0.08mm for Precision Instrument

    CuNi alloy Grade: Constantan, CuNi1, CuNi2, CuNi6, CuNi8, CuNi10, CuNi14, CuNi19, CuNi23, CuNi30, CuNi34, CuNi40 (6J40), CuNi44.


    Our product are in the form of wire, ribbon, strip, foil.


    Constantan (CuNi44)


    CuNi44, also called Constantan, has a very low temperature coefficient, high electrical resistance, high ductility and non-corroding properties. It is suitable for use at temperatures up to 600°C (1110°F). As a very malleable, very ductile alloy, it has a very good resistance to oxidation.


    The alloy is non-magnetic. It is suitable for electrical resistors, potentiometers, heating wires, heating cables and mats. Ribbons are used for heating of bimetals. Another field of application is manufacturing of thermocouples because it develops a high electromotive force (EMF) in association with others metals
