CuNi2Be or beryllium nickel copper UNS C17510 is a high conductivity copper-beryllium alloy used in applications requiring a combination of high thermal conductivity with moderate strength. CuNi2Be, supplied with certified mechanical properties, is fully heat-treated, and no additional treatment is needed. CuNi2Be is nonmagnetic and provides excellent resistance to thermal fatigue.

It is widely used in making battery probe , especially for production of modern electronic car battery.
