Abstract
A method is set forth for the production of shaped parts from a multi-component silver-copper alloy containing at least one metal from the group consisting of tin and indium and optionally zinc. The alloy is hot worked and then subsequently subjected to cold working, each of the cold working steps being preceded by a special equilibrating heat treatment. The invention resides in using the special equilibrating heat treatment to improve the cold workability of the alloy.
