(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.)

OhmAlloy049 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 OhmAlloy49 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.

OhmAlloy049 is manufactured from electrolytic copper and pure nickel. In finer wire sizes the alloy is designated as OhmAlloy49TC(Thermocouple).
