Constantan-CuNi44 Sheet (Plate Strip)
Constantan-CuNi44 Sheet (Plate Strip) 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 and ductile alloy, it has a very good resistance to oxidation.
Constantan-CuNi44 Sheet (Plate Strip) is non-magnetic. It is suitable for electrical resistors, potentiometers, heating strips, 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.
