METHOD FOR PRODUCING A SEMI-FINISHED PART FOR ELECTRICAL CONTACTS

The invention relates to a method for producing a strand-like, particularly band-like semi-finished part for electrical contacts, wherein the semi-finished part has a top side intended for making the electrical contact, said top side made from a silver-based composite material in which one or multip...

description The invention relates to a method for producing a strand-like, particularly band-like semi-finished part for electrical contacts, wherein the semi-finished part has a top side intended for making the electrical contact, said top side made from a silver-based composite material in which one or multiple metal oxides or carbon are embedded, and has a carrier layer supporting the composite material made of silver or a silver-based alloy, said method having the following steps: Powder-metallurgic production of a block made from the silver-based composite material, encasing of the block made of the composite material with a powder made primarily of silver, compressing the block, encased by the metal powder, to condense the metal powder, sintering the compressed block, reshaping the sintered block by extrusion pressing, creating a partial strand with a top side made from composite material and a bottom side made from silver or a silver-based alloy.
