1. Introduction
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.
