Copper Nickel Alloy is mainly made of copper and nickel. The copper and nickel can be melted together no matter what percentage. Normally the

resistivity of CuNi alloy will be higher if the Nickel content is larger than Copper content. From CuNi1 to CuNi44, the resistivity is from 0.03μΩm to

0.49μΩm. That will help the resistor manufacture choosing the most suitable alloy wire.


CUNI 90/10 is a copper-nickel alloy with low resistivity for use at temperatures up to 250°C.

Curpothal 15 is typically used for applications such as heating cables, fuses, shunts, resistors and various types of controllers.
