Durable metal strip with integrally bonded transverse portions
The patent US12030133B2 describes a novel metal strip composed of two distinct transverse portions: a first portion made from aluminum or an aluminum alloy, and a second portion made from a copper or copper alloy with a tensile strength of at least 360 MPa. These portions are integrally bonded through a butt seam that runs along the length of the strip. The first portion features a copper cladding layer along at least one edge, and the butt seam is positioned between this cladding layer and the second portion. The claims further specify various characteristics of the metal strip, including electrical conductivity, thickness ratios, and material compositions for both the base and cladding layers.
Additionally, the patent outlines a continuous manufacturing process for producing this metal strip. This process involves welding the first and second metal strips together along their longitudinal sides to form a butt joint. The welding can be achieved through methods such as beam welding or laser welding. The claims also detail pre-welding preparations, such as creating recesses or notches in the first metal strip to facilitate the bonding process. The resulting metal strip is intended for use as a semi-finished product or feedstock in electrical components, highlighting its potential applications in industries requiring high-performance materials.
