  • Publication number: 20180065206
    Abstract: A clad metal composite produced according to a method for edge-to-edge cladding of two or more different metals (such as aluminum and copper). The metals are joined next to each other to form an edge-to-edge or side-by-side clad bimetal. In one embodiment, nine metal strips are used to create the desired clad metal composite. The design includes strips of metal that have industry standard cut edges (such as, slit-cut edges). The clad metal composite may include multiple layers of metals positioned edge-to-edge.

  • Publication number: 20170298493
    Abstract: A method for producing a material that has the primary desirable properties that can be used for electrical terminal connectors. The present invention is directed at a clad material having high electrical conductivity, specific strength, good ductility, compatibility with joining materials, and low cost properties, and the method for making the material. In an aspect, the cladded material is made from one or more metals that collectively, have the properties discussed above. In an aspect, the cladded material is a transition-metal interconnector for electrical terminal connectors. In an exemplary aspect, the material is cladded aluminum and copper. The present invention relates to cladding materials built for use in connecting materials with different properties (e.g., aluminum and copper) in cathodes and anodes.

  • Patent number: 5607522
    Abstract: An electrical contact material having metal oxide particles dispersed in a silver metal matrix and having an easily brazeable backing layer is made free of internal oxide depletion zones by bonding a conventional internally oxidizable silver alloy to a thin backing layer of a second silver alloy to form a composite metal. The first silver alloy is selected to be internally oxidizable under selected oxidizing conditions. The second alloy is selected so that under the selected oxidizing conditions an oxygen-impenetrable barrier is quickly established on the surfaces of the composite formed by the second alloy. In that way, the first alloy layer is forced to be internally oxidized unidirectionally from the opposite surface of the composite to form the desired metal oxide dispersal extending substantially throughout the first alloy layer free of any internal oxide depletion zone in the first layer.
