ABSTRACT:
The present invention relates to composites having excellent combinations of bending strength, electrical conductivity, stress relaxation in bending and bend formability and having particular utility in electrical connector applications. The composites of the present invention have a core formed from a copper base alloy having an electrical conductivity of at least about 80% IACS and a clad formed from a copper-nickel alloy containing more than about 30% by weight nickel. Preferred composites are triclad composites formed from copper alloy C151 and MONEL 400 and having clad layer thicknesses of at least about 10%, most preferably at least about 20%, of the overall composite thickness.
