Specification :

Constantan alloy strip. CuNi44 Resistance constantan strip can be used to make wire-wound precision resistors, volume control devices, etc.
CuNi44 Resistance constantan strip is universally known as Constantan or Konstantan, its high specific resistance and negligible temperature coefficient of resistance are its most important attributes. For others, the fact that CuNi44 offers good ductitility, is easily
soldered and welded and has good resistance to atmospheric corrosion is more ignificant.
Main usage:
1) wire-wound precision resistors, volume control devices, etc
2) low temperature resistance heating applications
3) winding heavy-duty industrial rheostats and electric motor starter resistence
Resistivity: 0.49 ohm. Mm2/ m
German material code: 2.0842
