Definitions

  • the invention relates to an aluminum die-cast alloy and a structural component for a motor vehicle.
  • an aluminum alloy for die-casting of components with high elongation in the as-cast state is known. Further compositions for aluminum die-cast alloys are in the EP 1 719 820 A2 , the DE 10 2006 039 684 B4 , the DE 10 2010 055 011 A1 , the EP 2 653 579 A1 , the EP 2 865 773 A1 or the EP 1 443 122 B1 described.
  • manganese is partially added to the alloy in order to reduce the tendency to stick to the die and thus improve the demoldability of the finished cast parts.
  • the manganese content is typically between 0.3 and 0.8% by weight. If the manganese content is less than 0.3% by weight, there is an increased tendency to stick and a complex casting can no longer be removed from the mold. Such a tendency to stick is not only disruptive to the process and the dimensional accuracy, but also leads to increased wear on the casting tool.
  • an excessively high proportion of manganese of more than 0.8% by weight due to the formation of coarse, intermetallic precipitates, causes the material to become brittle and thus a reduction in ductility or deformability.
  • Molybdenum is added to the alloy. By adding Molybdenum can counteract the increased tendency to stick by reducing the manganese content.
  • Molybdenum as an element is relatively expensive, which increases the cost of such a raw material.
  • From the EP 1 443 122 B1 is an aluminum alloy for the die-casting of components with high elongation in the as-cast state.
  • the inventors have surprisingly found that a reduction in the molybdenum content such that molybdenum is present in a proportion of 0.001 to 0.048% by weight, in particular 0.001 to 0.043% by weight, in particular 0.024 to 0.043% by weight, and a simultaneous use of chromium promote the reduction of the tendency to stick and the increase in ductility.
  • a proportion of molybdenum has also proven to be very suitable with regard to good demoldability and high ductility.
  • a proportion of Molybdenum replaced by chromium.
  • even very small amounts of chromium are sufficient to achieve a significant effect.
  • the following additional optional or facultative alloy components are provided in the aluminum die-cast alloy according to the invention: 0.001 to 0.15% by weight of iron and / or 0.004 to 0.15% by weight of titanium and / or 0.01 to 0, 2% by weight zirconium and / or 0.008 to 0.02% by weight strontium and / or 0.001 to 0.1% by weight vanadium.
  • iron as a contaminant element always occurs in small quantities in the alloy, ie the lower the iron content, the more expensive the pure aluminum.
  • the silicon content of 7.5 to 11.5% by weight present in the alloy according to the invention ensures sufficient strength and a high mold filling capacity of the aluminum die-cast alloy according to the invention. Furthermore, silicon counteracts solidification voids during cooling.
  • the manganese content in the alloy can be reduced to a proportion of 0.25 to 0.6% by weight, which improves the demoldability and result in higher ductility.
  • the surprising thing about the alloy composition according to the invention is therefore that small proportions of chromium make it possible to reduce the proportion of molybdenum, which significantly improves both the elongation at break and the demoldability.
  • chromium is provided in a proportion of 0.04 to 0.05% by weight, in particular 0.04 to 0.048% by weight, the tendency of the material to stick can be further reduced and the ductility of the same can be optimized.
  • manganese is present in a proportion of 0.35 to 0.6% by weight, in particular 0.45 to 0.55% by weight. Such a proportion of manganese has proven to be particularly advantageous with regard to a low tendency to stick.
  • a structural component for a motor vehicle, produced from an aluminum die-cast alloy according to the invention, is specified in claim 4.
  • Such a structural component can be used for a wide variety of purposes in motor vehicles, since it has the required strength as well as sufficient ductility and good demoldability.
  • a very advantageous development of the structural component can consist in that the structural component is designed as a thin-walled strut mount, battery tray or connecting part and is manufactured without heat treatment.
  • the aluminum die-cast alloy according to the invention is particularly well suited for the components mentioned; however, it can also be used for other components. By dispensing with heat treatment of the structural component, warping of the same is avoided, so that a high level of accuracy of the components can be achieved.
  • the aluminum die-cast alloy according to the invention was used achievable improved demoldability can be clearly demonstrated, as can also be seen in the following table.
  • the mechanical parameters, ie the strength and the ductility, were determined on flat tensile specimens with an average wall thickness of 3.5 mm.
  • composition of the base alloy used was as follows: AlSi10Fe0.13Mg0.04Ti0.09Zr0.15Sr0.012. alloy composition Yield strength Rp0.2 in MPa Elongation at break A5 in% Demoldability 1 Base + Mn0.66 123 6.7 250 2 Base + Mn0.5 119 8.8 55 3 Base + Mn0.42 115 9.2 7th 4th Base + Mn0.41Mo0.15 124 10.0 40 5 Base + Mn0.55Mo0.10 122 8.5 107 6th Base + Mn0.51Mo0.03Cr0.048 122 10.7 250 7th Base + Mn0.35Mo0.03Cr0.047 121 13.2 250
  • Alloy 1 according to the prior art could be demolded very well, but had a very low elongation at break due to the high manganese content.
  • the manganese content was reduced, which, however, led to an increased tendency to stick and thus poorer demoldability. Basically, the reduction in the manganese content is also noticeable in a higher elongation at break with a slightly lower yield point.
  • Alloys 6 and 7 are two different versions of the aluminum die-cast alloy according to the present invention. Compared to alloys 4 and 5, the molybdenum content was reduced and chromium was also added. As a result, the elongation at break increased to values acceptable for use in motor vehicles and there was a very low tendency to stick and therefore very good demoldability. The strength of the two alloys 6 and 7 is also sufficient for the purpose for which they are intended.
  • the table shows the above-described effect of the proportions of molybdenum and chromium used for the properties of the aluminum die-cast alloy.
