Abstract
A process is described for the manufacture of strip comprising a base metal substrate, a coating which has been electrodeposited on selected surface portions of said substrate and consists of precious metal or a precious metal alloy and, if desired, an intermediate diffusion barrier layer consisting particularly of nickel. The resulting strip constitutes a semifinished product for use in the making of electric contacts. When the coating has been electrodeposited, the strip is subjected to a recrystallizing annealing and to a rolling operation, preferably a cold-rolling operation.
