Low Resistance Alloy Constantan Foil
Constantan( Ualloy049)
(Common Name: CuNi45, NC50.Cuprothal, Alloy 294, Cuprothal 294,
Nico, MWS-294, Cupron, Copel, Alloy 45, Neutrology, Advance, CuNi
102, Cu-Ni 44, Konstantan,constantan.)
Ualloy049 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 Ualloy049 are temperature-stable potentiometers, industrial rheostats and
electric motor starter resistances.
The combination of negligible temperature coefficient and high
resistivity makes the alloy particulary suitable for the winding of
precision resistors.
Ualloy049 is manufactured from electrolytic copper and pure nickel. In finer
wire sizes the alloy is designated as Ualloy049TC(Thermocouple).
