- Aluminum alloy sheets are playing an increasing role as compared to
- Aluminum sheets made of a hardenable Al-Mg-Si alloy of class AA6XXX Aluminum alloy sheets of this class are used in the solution-treated state T4 and then subjected to a heat aging to achieve a higher ultimate strength in the state T6.
- AlMg alloys of the type AA 5xxx with Mg contents of more than 3% by weight, in particular more than 4% by weight, are increasingly prone to intercrystalline corrosion, for example when exposed to elevated temperatures.
- ⁇ -AlsMg3 phases precipitate along the grain boundaries, which are referred to as ⁇ -particles and can be selectively dissolved in the presence of a corrosive medium.
- Standard test according to ASTM G67 in which the samples are exposed to nitric acid and the mass loss of the aluminum sheet is measured.
- ASTM G67 Standard test according to ASTM G67, in which the samples are exposed to nitric acid and the mass loss of the aluminum sheet is measured.
- ASTM G67 a corresponding heat load of the components in the application is simulated by a prior sensitization annealing at temperatures of 130 ° C. for 17 hours.

However, the values for the yield strength R p0 , 2, which is a measure of the resistance of the sheet to plastic deformation, are too low to significantly reduce the yield

- the chromium content should be limited to values of less than 0.05% by weight, preferably less than 0.01% by weight.
- Zr which, since it usually has to be added, is not listed here in detail.
- Zinc could have a negative effect on the corrosion resistance of the aluminum alloy strip and should therefore be limited to a maximum of 0.2% by weight.
- Titanium is commonly added in continuous casting of the aluminum alloy as a grain refining agent, for example in the form of Ti-boride wire or rods.
- too high Ti contents in turn have a negative effect on the forming properties, so that a limitation of the Ti content to a maximum of 0.20 wt .-% is desired.

This also applies analogously to zirconium and scandium which, if at all, are only present in traces in the aluminum alloy.

For example, a higher yield strength of more than 200 MPa can reduce the final thicknesses of the aluminum alloy strip and thus a allow further reduction of the weight of the molding produced therefrom, for example a vehicle component.
- the increase in the uniform expansion to at least 15% or the increase in the Brucheinschnürung Z to at least 55% means that the aluminum alloy strip or sheet according to the invention can be used in complex forming processes and, for example, complex shaped moldings can be produced with a few forming steps.

- This is followed by the Hot rolling the rolling ingot in step 3 at a temperature of 280 ° C to 500 ° C to a hot strip.
- the limitation of Abwalzgrads to 10% to 45% causes in the subsequent intermediate annealing according to step 5 by recrystallization a mean grain size of more than 20 ⁇ can be achieved.
- the implementation of the last intermediate annealing of the cold-rolled aluminum alloy strip at 300 ° C to 500 ° C provides for the final cold rolling step 6, a recrystallized structure with grain sizes of more than 20 ⁇ available. Steps 4 and 5 can possibly

- FIG. 2a) and 2b) show schematically areas of application of the invention
- Corrosion behavior of the aluminum alloy strips according to the present invention opens up further applications for the
- Table 1 shows a total of seven different ones
- Experiments 1, 2 and 9 included aluminum alloys whose Mg, Mn or Cr content are outside the range according to the invention.
- the Mg content is too small and the contents of Mn and Cr are too large. Too high values for Cr and slightly increased values for Mn also include Comparative Example No. 2.
- Comparative Example No. 9 in turn has clearly too large values for Mn and Cr. The hot strips made of different aluminum alloys were then cold rolled before the last one according to the specifications in Table 2
- Annealing temperature was 240 ° C in all experiments. The annealing was carried out in the coil, wherein the metal temperature of the annealing temperature was maintained for a period of at least 0.5 h.
- Table 2 also indicates the final thicknesses a 0 , which are approximately between 0.7 mm and 1.7 mm. In Table 2, the Abwalzgrade which are outside the range of the invention, underlined. Comparative Examples Nos. 1 and 6 have excessive degrees of finish before intermediate annealing, whereas Comparative Example No. 3 has too low final rolling degree after intermediate annealing.
- the mean grain size ie the average grain diameter, was measured. For this purpose, samples were taken from the tapes and anodized longitudinal blanks according to the Barker method. Under the microscope, the samples were measured according to ASTM E1382 and the mean grain size determined by the mean grain diameter.
- Table 3 also shows the mass loss values in a corrosion test according to ASTM G67 (NAMLT), in which the samples were previously subjected to a simulated thermal stress for 17 hours at 130 ° C.
- NAMLT ASTM G67
- Comparative Example No. 1 which has a markedly increased Mn content, for example, the uniform elongation A g decreases to 10.6%. Also, the too low Mg content of Comparative Example No. 1 counteracts large elongation values.
- Comparative Example No. 2 having an increased Cr content at a slightly excessive Mn content shows fracture necking values Z that are less than 50%, indicating a deteriorated forming performance.
- Fracture necking Z represents precisely the property of the material, in the case of large deformations via a cross-sectional reduction material for the forming to provide without tearing. Due to the higher Mn contents or Cr contents, the average particle size of 10 or 15 ⁇ m has no negative influence on the corrosion properties of these samples. Comparing Comparative Example No. 3 with the invention
- Exemplary embodiment No. 4 makes it clear that the yield point R p0 , 2 can be set via the adjustment of the degree of rolling during final rolling after the intermediate annealing .
- Embodiments Nos. 4, 5 and 8 show that about
- the yield strength R p o, 2 can be increased to values up to 211 MPa without causing significant losses in the area of the characteristic values for the transformation, such as the uniform elongation A g or Z.
- Aluminum alloy as Examples 3, 4, 5 and 8 can be very clearly recognized the influence of the adjustment of the average grain diameter by limiting the degree of rolling during cold rolling before the last intermediate annealing.
- the intermediate annealing produces a relatively fine grain having an average diameter or an average grain size of 13 ⁇ m, which produces the
- Comparative Example No. 6 is classified as not resistant to intergranular corrosion.
- the embodiments according to the invention show that the yield strength R p o, 2 are increased to values of up to 270 MPa by using degrees of rolling in final cold rolling of 40% to 60%.
- the higher Mg content of up to 5.2 wt .-% in the embodiment no. 12 contributes to the significant increase in the yield strength R p o, 2 at.
- a comparison of the embodiments of the invention No. 9, 10 and 11 shows that the corrosion resistance depends strongly on the choice of Abwalzgrades before the last intermediate annealing and thus from the mean grain diameter or the average grain size.
- the Mg content is increased over Embodiment No. 9, which in principle may lead to inferior corrosion resistance to intergranular corrosion.
- Aluminum alloy strip can be provided which
- Vehicle components is particularly well suited and can be produced inexpensively due to the use of non-hardenable aluminum alloy.
