Product Description

Cuni44 CU-NI-Mn Copper Nickel Alloy resistance Constantan Strip
(Common Name:Constantan CuNi44,NC50.Cuprothal, Alloy 294, Cuprothal 294, Nico, MWS-294, Cupron, Copel, Alloy 45, Neutrology, Advance, CuNi 102, Cu-Ni 44, Konstantan,)

Cuni44 is a copper-nickel alloy (Cu56Ni44 alloy) characterized by high electrical resistance, high ductility and good corrosion resistance. It is suitable for use at temperatures up to 400°C
Typical applications for CuNi44 are temperature-stable potentiometers, industrial rheostats,electric motor starter resistances and strain gauge.
The combination of negligible temperature coefficient and high resistivity makes the alloy particulary suitable for the winding of precision resistors.
CuNi44 is manufactured from electrolytic copper and pure nickel. In finer wire sizes the alloy is designated as Cuni45(Thermocouple).
Product Description
Constantan Strip with moderate resistivity and low temperature coefficent of resistance with a flat resistance/temperature curve over a wider range than the "manganins". Constantan also shows better corrosion resistance than the man ganins. Uses tend to be restricted to ac circuits.

Constantan is also the negative element of the type J thermocouple with Iron being the positive; type J thermocouples are used in heat treating applications. Also, it is the negative element of the type T thermocouple with OFHC Copper the positive; type T thermocouples are used at cryogenic temperatures.
