0.25mm * 3.0mm Copper Nickel Alloy Hecnum Tape On DIN 125 Reels Bright Surface

0.25mm*3.0mm Copper nickel alloy Hecnum Tape on DIN 125 reels


(Common Name:CuNi44,NC50.Cuprothal, Alloy 294, Cuprothal 294, Nico, MWS-294, Cupron, Copel, Alloy 45, Neutrology, Advance, CuNi 102, Cu-Ni 44, Konstantan,constantan.)


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 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.

CuNi44 is manufactured from electrolytic copper and pure nickel. In finer wire sizes the alloy is designated as CuNi44TC(Thermocouple).
