Definitions

  • the invention relates to an aluminum alloy, in particular an aluminum alloy which contains aluminum, magnesium and silicon as alloy components, and in die casting and related processes, e.g. can be processed by squeezecasting, or by thixoforming.
  • this aluminum alloy is also suitable for forging in the partially liquid state (thixoforging).
  • the die-casting process and the related processes are of particular economic and technical importance among the shaping processes. Die casting in particular has developed into a technology that allows the production of parts with high quality standards and high productivity. The use of vacuum and squeezecasting should also be mentioned here. In order to be able to exploit the potential of the shaping processes mentioned, suitable alloys must also be available.
  • alloys are also good mechanical properties, such as high elongation at break, high yield strength and tensile strength. These properties are largely determined by the structure of the alloy.
  • annealing In the case of aluminum alloys, which contain aluminum, silicon (main alloy element) and magnesium as alloy components, the required high mechanical strengths are achieved by heat treatment. In the case of high-temperature annealing (usually at 490 ° to 530 °), the eutectic silicon is molded in and thus the elongation at break is improved. Quenching from the annealing temperature to room temperature and subsequent aging (typically at temperatures between 150 ° to 180 °) improves the yield strength and tensile strength.
  • annealing has several disadvantages, in particular for die-cast parts. Enclosed oxide skins and compressed gas inclusions due to turbulent mold filling that are typical for die-casting processes form defects during annealing which can lead to component failure.
  • the last-mentioned problem does not occur in thixoforming with its quasi-laminar mold filling, but here - just as in the case of die casting - the mold release agent can cause the surface to gas up.
  • the dissolved or trapped gas can then become noticeable in the form of bubbles during annealing and can also lead to surface defects and a deterioration in the mechanical strength values.
  • Die-cast parts and especially thixoforming parts are also characterized by the fact that they can be manufactured very close to their final dimensions. However, the annealing with the subsequent quenching leads to a delay which nullifies this process advantage.
  • Aluminum alloys which contain aluminum, magnesium and silicon as alloy components and are used in the above-mentioned shaping processes, usually have an iron content of about 0.5 to 1.2% by weight to reduce the tendency to stick. However, this high iron content reduces the elongation at break and ductility in the die-cast part and also impairs the corrosion resistance.
  • die-casting alloys of the aluminum-magnesium-silicon type with magnesium contents between 3 and 9% by weight are known.
  • these alloys contain the high iron contents already described.
  • no special measures for refining the alloy structure have been described. The mechanical properties of these materials are not outstanding.
  • a well-known low-iron alloy of the aluminum-magnesium-silicon type is that known under the name MAGSIMAL-59 ® is available from Aluminum Rheinfelden GmbH.
  • MAGSIMAL-59 ® is available from Aluminum Rheinfelden GmbH.
  • this alloy mainly consists of 5.0 to 5.5% by weight of magnesium, 1.8 to 2.5% by weight of silicon with a max. 0.25 wt% iron.
  • this alloy contains a manganese additive of 0.5 to 0.8% by weight, since this reduces the solubility of the iron in the alloy melt and therefore the die-casting tool cannot be attacked.
  • a high addition of manganese leads to the separation of coarse manganese-containing phases, which is known from the art.
  • the aim of the present invention is to overcome the above disadvantages and to develop an aluminum alloy which, in addition to aluminum, magnesium and silicon, contains further main alloy constituents and which in particular has the following properties: good mechanical properties in the as-cast state, particularly also high ductility; good castability and easy release from mold due to a lack of tendency to stick in the mold; sufficient design stability at high temperatures; good weldability; and good corrosion resistance.
  • this goal is achieved by an alloy which has the following composition: 2.5 to 7.0% magnesium, 1.0 to 3.0% silicon, 0.3 to 0.49% manganese, 0.1 to 0 , 3% chrome,
  • titanium max. 0.15%
  • iron max. 0.00005%
  • calcium max. 0.00005%
  • sodium max. 0.0002%
  • phosphorus other impurities in an amount of max. 0.02% by weight and the balance aluminum.
  • a zircon content of 0.05 to 0.2% is provided.
  • alloy 1 is the well-known Magsimal-59® alloy
  • alloy 2 is an alloy whose composition corresponds to the alloy according to the invention, but does not contain chromium
  • alloy 3 is an alloy according to the invention.
  • the mechanical property values summarized in the table below were determined in a tensile test on die-cast flat tensile specimens of the three alloys in accordance with DIN 50 148. The values given correspond to the mean values from 20 tensile tests each.
  • the table shows that the alloy 3 according to the invention exceeds the alloys 1 and 2 in the parameters of tensile strength and elongation at break under the test conditions.
  • the alloy according to the invention like alloy 2, has a significantly higher value than the known alloy 1 at 5.9%.
  • the values given in the table are rather low due to casting-related shrinkage porosity and only serve to compare the materials.
  • 3 elongations at break of up to 20% were determined with the alloy according to the invention.
  • the alloy 3 according to the invention is to be preferred since, due to its special composition, it achieves in particular higher tensile strengths with high elongation values than the two alloys 1 and 2.
