ABSTRACT:
Nesting electrical connectors comprising a substrate and a silver-nickel-carbon electrodeposit atop the substrate. The electrodeposit is at least about 0.5 micrometers thick, and comprises about 10 to about 25 atomic percent nickel which is dispersed as a discontinuous phase throughout a continuous phase of the silver and has a Scherrer grain size less than about 5 nanometers. The carbon comprises about 5 to about 15 atomic percent of the deposit and has a non-crystalline graphite structure.
