ALLOY 390® UNS C17460

Alloy 390 strip combines the best attributes of copper beryllium alloys -- the strength of the Alloy 25 and the conductivity of Alloy 3.  In addition, Alloy 390 has excellent fatigue strength and stress relaxation resistance at elevated temperatures.

Alloy 390 was specifically designed for use in applications where durability, power management and/or harsh operating environments are a concern.
