Product Description

Constantan copper nickel foil 6j40 Ultra-thin resistance strip
Tankii, as a big manufacturer and exporter in China on the line of electric resistance alloy, we can supply all kinds of electric resistance alloy wire and strips (resistance steel wire and strips),
Material: CuNi1, CuNi2, CuNi6, CuNi8, CuNi14, CuNi19, CuNi23, CuNi30, CuNi34, CuNi44.

1. 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.

Our company produce alloy foil, metal foil, steel foil thickness 0.005mm-0.1mm(5um-100um), width 1mm-1330mm.
