ABSTRACT:
In the manufacture of a formed contact part of a metal alloy, wherein the formed part is shaped in one or more manufacturing operations without the removal of metal to produce a contact element, the improvement which comprises forming from the alloying constituents a composite material in which the alloying constituents are heterogeneously embedded, the composite material being formed into the contact part without the removal of metal and, after forming, heating the contact part so as to convert the composite material into a homogeneous alloy. The process is particularly applicable to silver-palladium alloys where the alloy would not itself be suitable for the forming operation.
