Method for manufacturing an electrically conductive metallic strip

The invention relates to a method for the manufacture of an electrically conductive metallic strip for the production of plug contact elements. A starting strip of copper or a copper alloy having an initial thickness which is greater than its final thickness is tin-plated. Subsequently, the tin-plat...

Beschreibung
Zusammenfassung:	The invention relates to a method for the manufacture of an electrically conductive metallic strip for the production of plug contact elements. A starting strip of copper or a copper alloy having an initial thickness which is greater than its final thickness is tin-plated. Subsequently, the tin-plated copper strip is deformed by rolling. This rolling process reduces both the thickness of the layer of tin and the thickness of the underlying copper strip.
