ABSTRACT:
The present invention relates to a copper base alloy consisting essentially of from about 3.5% to about 6.0% aluminum, from about 0.1% to about 3.0% nickel, from about 0.03% to about 1.0% magnesium and the balance essentially copper. The alloys of the present invention have been found to be cost effective and easily processable. They have also been found to have particular utility in electronic and electrical applications such as electrical connectors.
