CONSTANTAN WIRE

Constantan wire, also called CuNi44 Wire 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, Constantan wire has a very good resistance to oxidation.

The alloy wireis 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.

Wire Diameter: 0.05mm-10.0mm, 0.002 Inch to 0.3937 Inch
