Abstract
An electrical contact element is made of material which is resistant to metal migration and which contains a major proportion by weight, at least two metallic components which are soluble in each other and form a composite material. At least one of the components consists of a noble metal, and the metallic components are heterogeneously embedded in the composite material as pure metallic components. A process for making such a contact element comprises forming jacket wires, made of the metallic components, into clusters and metallurgically joining the wires by plastic shaping to form the composite material.
