CuNi44 resistance wire / constantan / copper nickel alloys

is universally known as Constantan or Konstantan, its high specific resistance and negligible temperatuer coefficient of resistance are its most important attributes. For others, the fact that CuNi44 offers good ductitlity, is easily soldered and welded and has good resistance to atmospheric corrosion is more significant.  

Main usage:
1) wire-wound precision resistors, volume control devices, etc
2) low temperature resistance heating applications
3) winding heavy-duty industiral rheostats and electic motor starter resistance

Resistivity: 0. 49 ohm. Mm2 / m

German material code: 2.0842
 

Form of Delivery
CuNi44 is supplied in the form of wires with dimensions from 0.03 to 6.0 mm, in bare condition. Enamelled wires are available in dimensions between 0.09 and 1.0 mm. CuNi44 can also be supplied in form of stranded wire, ribbon, flat wire and rods.
