Abstract: Disclosed are welds formed from improved resistance spot welding. Resistance spot welding includes positioning a first metal sheet and a second metal sheet between two electrodes, contacting the two electrodes together on to opposing surfaces of the first metal sheet and the second metal sheet, and applying at least a minimum current to the first metal sheet and the second metal sheet through the two electrodes to form a weld having a minimum weld size to join the first metal sheet with the second metal sheet. At least one of the first metal sheet and the second metal sheet is a fusion alloy where the composition of at least one outer layer of the sheet is different from the composition of the core of the sheet.

Abstract: In a first aspect, the invention provides aluminum alloy comprising the following composition, all values in weight %: Si 0.25-1.5 Cu 0.3-1.5 Fe up to 0.5 Mn up to 0.1 all other elements including Mg being incidental and present (if at all) then in an amount less than or equal to 0.05 individually, and less than or equal to 0.15 in aggregate, the balance being aluminum. In a second aspect, the invention provides a composite aluminum sheet product comprising a core layer and at least one clad layer wherein the at least one clad layer is an aluminum alloy comprising the following composition, all values in weight %: Si 0.25-1.5 Cu 0.3-1.5 Fe up to 0.5 Mn up to 0.1 all other elements including Mg being incidental and present (if at all) then in an amount less than or equal to 0.05 individually, and less than or equal to 0.15 in aggregate, the balance being aluminum.

Abstract: Disclosed are high-strength aluminum alloys and methods of making and processing such alloys. More particularly, disclosed is a 6XXX series aluminum alloy exhibiting improved mechanical strength, formability, corrosion resistance, and anodized qualities. An exemplary method includes homogenizing, hot rolling, solutionizing, and quenching. In some cases, the processing steps can further include annealing and/or cold rolling.

Abstract: Provided herein are novel, high-forming multi-layer aluminum alloy packages that include a core layer and one or more cladding layers.

Abstract: A component, especially a hot gas component of a turbomachine, has at least one passage (7, 7?), especially a cooling passage, which is embedded in an outer wall (5) of the component (1) of the turbomachine and basically extends parallel to the surface (6) of the component (1). The component (1) has a basic body (8) and at least one coating (9) which is applied to the basic body on the outside, and the passage (7, 7?) on one hand is formed by a cavity which is formed in the basic body (8), and on the other hand is closed off towards the surface (6) of the component (1) by the coating (9).
