CuNi44 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
