ABSTRACT:
The present invention relates to copper-nickel alloys having improved ductility at elevated temperatures. The alloys consist essentially of about 5% to about 45%, preferably about 5% to 35% nickel, about 0.4% to about 1.1%, preferably about 0.6% to about 1% manganese, about 0.003% to about 0.04%, preferably about 0.008% to about 0.03% phosphorous and the balance essentially copper. The alloys described herein have particular utility in brazed articles or assemblies.
