Definitions

  • the invention relates to an aluminum alloy strip and uses therefor.
  • Semi-finished products and components for motor vehicles have to meet different requirements depending on their location and intended use in the motor vehicle, in particular with regard to their mechanical properties and their corrosion properties.
  • the mechanical properties are predominantly determined, for example, by the rigidity, which depends in particular on the shape of these parts.
  • the strength has a minor influence, although the materials used must not be too soft.
  • Good formability is very important, since the components and semi-finished products generally go through complex forming processes, for example in the manufacture of door interior parts. This applies in particular to components that are manufactured in a one-piece sheet metal shell construction, e.g. a sheet metal inner door with integrated window frame area. By saving joining operations, such components have cost advantages compared to an attached profile solution for the window frame.
  • corrosion resistance also plays a major role in motor vehicles, since motor vehicle components such as door interior parts are exposed to splash water, condensation water or condensation water. It is therefore desirable that the motor vehicle components have good resistance to various corrosion attacks, in particular to intergranular corrosion and to filiform corrosion.
  • Filiform corrosion means a type of corrosion that occurs in coated components and shows a thread-like course. Filiform corrosion occurs in high humidity in the presence of chloride ions.
  • Hardenable AA 6xxx alloys have high strengths as well as good resistance to intergranular corrosion and filiform corrosion, but are much more difficult to form than AA 8006 and are therefore not particularly suitable for the production of complex components such as door parts.
  • the production of semi-finished products and components from an AA 6xxx alloy is quite complex and expensive, since it requires continuous annealing as a special process step.
  • AA 5xxx alloys with a high magnesium content combine high strength with quite good formability.
  • the formability is not as good as that of steel solutions, which leads to restrictions in the design of the components.
  • these alloys tend to intergranular corrosion.
  • Steel materials are very easy to form, but have the same rigidity and a weight disadvantage and are also prone to corrosion.
  • the present invention is based on the object of providing an aluminum alloy strip which is highly malleable, medium-strength and corrosion-resistant. Should continue advantageous uses for the tape are provided. This object is achieved with an aluminum alloy strip and a use of the strip with the features of claims 1 or 8 and 9.
  • the aforementioned object is achieved according to the invention in that the alloy components of the aluminum alloy have the following proportions in percent by weight: Fe ⁇ 0.80%, Si ⁇ 0.50%, 0.90% ⁇ Mn ⁇ 1.50%, Mg ⁇ 0.25%, Cu ⁇ 0.20%, Cr ⁇ 0.05%, Ti ⁇ 0.05%, V ⁇ 0.05%, Zr ⁇ 0.05%,
  • the aluminum alloy of the aluminum alloy strip according to the invention is based on the alloy type AA 3xxx, in particular AA 3103 (AlMn1). Such alloys have a very good formability, but are usually too soft for many applications such as components of motor vehicles.
  • the addition of certain alloying elements, in particular Mg and Cu, can increase the strength of the aluminum alloy, but this also leads to a significant reduction in ductility and thus in turn to poorer formability.
  • the combined proportion of copper and magnesium in the aluminum alloy of the aluminum alloy strip according to the invention must be precisely controlled in order to achieve the desired mechanical properties, namely an elastic limit R p0.2 of at least 45 MPa with a uniform expansion A g of at least 23% and an elongation at break A 80mm of at least 30%, with good corrosion resistance.
  • an elastic limit R p0.2 of at least 45 MPa with a uniform expansion A g of at least 23% and an elongation at break A 80mm of at least 30%
  • a combination of Mg and Cu between 0.15 and 0.25% by weight achieves a combination of strength and formability of the aluminum alloy that is advantageous for the applications mentioned.
  • the combined proportion of magnesium and copper must be at least 0.17% by weight so that the aluminum alloy of the aluminum alloy strip according to the invention achieves sufficient strength, in particular with an elastic limit R p0.2 of at least 45 MPa.
  • the combined proportion of Mg and Cu must be limited to at most 0.25% by weight, preferably at most 0.23% by weight, in particular at most 0.20% by weight, since otherwise uniform expansion A g and elongation at break A 80 mm fall too much, namely below 23% for A g or below 30% for A 80mm .
  • the combined proportion of magnesium and copper is generally understood to mean the sum of the two individual proportions for Mg and Cu in% by weight.
  • the aluminum alloy of the aluminum alloy strip according to the invention has a Cu content of at most 0.20% by weight, preferably at most 0.10% by weight, in particular at most 0.05% by weight, and a magnesium Proportion of at most 0.25% by weight, preferably at most 0.2% by weight.

  • the Mg content of the aluminum alloy of the aluminum alloy strip according to the invention is greater than the Cu content of the aluminum alloy. In this way, the corrosion behavior of the aluminum alloy of the aluminum alloy strip according to the invention, in particular with regard to filiform corrosion, can be further improved.
