Abstract
The invention refers to a corrosion-proof solderable system of layers which is applied to a support and is made of a solderable layer and a corrosion-protection layer covering the solderable layer and protecting it from complete oxidation. In order to create a layer system which is simpler and cheaper to manufacture, the solderable layer contains a proportion of oxidizable metal. The corrosion-protection layer is made by oxidation of the solderable layer on its free surface.
