Definitions

  • the invention relates to a body panel, in particular for the outer skin of passenger cars, made of an alloy of the AIMgSi type.
  • AIMgSi alloys for body panels in automobile construction is known, for example, from US-A-4,082,578 and US-A-4,589,932.
  • the alloys also contain significant amounts of copper and manganese.
  • the AA6063 alloy which can also be hardened and welded, is widely used for extruded products.
  • the inventor has set itself the goal of creating a body panel of the type mentioned at the outset which fulfills the requirements mentioned above and, moreover, can be produced more cost-effectively than the customary AIMgSi body panels.
  • the alloy has 0.2 to 0.6% Si, 0.4 to 0.9% Mg, max. 0.35% Fe, max. 0.1% Cu, max. 0.1 Mn, max. 0.1 Cr, max. 0.1% Zn, max. 0.1% Ti and other elements individually up to max. 0.05%, total max. 0.15%, and aluminum as the rest.
  • All salary data are in% by weight.
  • the preferred content range is 0.45 to 0.55% for Si and 0.55 to 0.65% for Mg.
  • Fe, Cu and Cr are expediently limited as follows: Fe 0.15 to 0.25%, Cu max. 0.05%, Cr max. 0.05%.
  • the alloy according to the invention can be processed according to the process steps known for AIMgSi alloys by hot and cold rolling into sheets with subsequent cold and / or hot hardening.
  • the alloy according to the invention has somewhat lower mechanical strength values, but surprisingly hardens at lower temperatures than the correspondingly higher-alloyed alloys according to the prior art.
  • the forming properties of sheets made from the alloy according to the invention are no worse than the optimized forming properties of the body panels according to the prior art.
