ABSTRACT:
Improved properties are obtained in copper alloys containing from 7 to 14% nickel, from 1.5 to 3.3% tin, plus iron and/or cobalt in an amount from 0.1 to 3% each, by hot rolling, cold rolling, annealing and cold rolling, all under defined conditions. The resultant alloys are characterized by good strength, good bend properties, good solderability and low contact resistance.
