  • AL-MG-ZN WROUGHT ALLOY PRODUCT AND METHOD OF ITS MANUFACTURE
    Publication number: 20150284825
    Abstract: An aluminum alloy wrought product including, in wt. %, Mg 3.0 to 7.0, Zn 0.6 to 2.8, Mn 0 to 1.0, Cu 0 to 2.0, Sc 0 to 0.6, at least one element selected from the group of Zr 0.04 to 0.4, Cr 0.04 to 0.4, Hf 0.04 to 0.4 and Ti 0.01 to 0.3; Fe maximum 0.3, Si maximum 0.3, inevitable impurities, and balance aluminum. The range for the Zn-content in wt. % is a function of the Mg-content according to: lower-limit of the Zn-range: [Zn]=0.34[Mg]?0.4, and upper-limit of the Zn-range: [Zn]=0.34[Mg]+0.4.

  • Weldable metal article
    Patent number: 8784999
    Abstract: The invention relates to an extruded or rolled clad metal article having a core metal layer and a cladding metal layer on at least one surface of the core layer, wherein the metals of the core metal layer and the cladding metal layer are each aluminum alloys, preferably an aluminum-magnesium alloy, having at least Sc in a range of 0.05% to 1%, and wherein the Sc-content in the core metal layer is lower than in the cladding metal layer. This further relates to a welded structure incorporating such a metal article.
