ALLOY 25

Alloy 25, by Materion Performance Alloys (MPA), provides the highest strength of any copper beryllium alloy along with electrical conductivity that is considerably greater than other high-strength copper alloys.

Since MPA Alloy 25 is heat treated, it provides excellent formability and ductility with good stress relaxation resistance and high fatigue strength.  It is non-magnetic and non-galling.
