CuNi2
Characteristics and Applications
This resistance alloy possesses good anti-corrosion properties, as well as particularly low specific electrical
resistivity and is therefore suited to low impedance resistance applications.
We can guarantee a specific electrical resistivity value within a tolerance of +/-10%.
