45/55 Ni Cu Resistance Wire (For Springs)
Nickel-Copper Base Wire for wire springs, flat springs and wire products
A Nickel-Copper alloy wire used mainly for its medium range electrical resistivity and very low temperature-coefficient of resistance.
45/55 Ni Cu Resistance Wire is also known as Constantan, Hecnum, Eureka, Ferry, and Advance.
- Low expansion alloy. Maintains near constant dimensions over the range of normal atmospheric temperatures.
- Low coefficient of expansion from cryogenic temperatures to about +500°C (+930°F). Retains strength and toughness at cryogenic temperatures.
Power resistors, shunts, thermocouples and wire-wound precision resistors having operating temperatures up to 400 °C (750 °F).
