Definitions
- the invention relates to a method for producing an aluminum alloy, in particular for die casting.
- AlSiMg alloys especially the AlSi9MgMnSr alloy, which are sold under different trade names such as "Silafont 36", "Aural 2" and the like, are mostly used for the production of die-cast components (see, for example, the document: Koch H. et al. : “Silafont - 36 - The new low-iron high pressure casting alloy", Light Metals, 1995, pages 1011-1018 .).
- the iron is largely replaced by manganese.
- improvements in elongation are expected due to the reduced iron content and strontium addition.
- these die cast alloys are characterized not only by excellent castability but also by very good elongation in the cast state, maximum elongation after heat treatment and, moreover, by very good corrosion resistance.
- the object of the invention is therefore to provide a simple process for producing an AlSi9MgMnSr alloy which has at least as good properties as the commercially available AlSi9MgMnSr alloys.
- the master alloy is an aluminum alloy which contains the remaining manganese, the entire strontium and optionally iron and possibly the remaining magnesium of the aluminum alloy to be produced, ie an AlMnSr alloy which optionally additionally contains Fe and / or Mg, ie B an AlMnSrFe, AlMnSrMg or AlMnSrFeMg alloy.
- the manganese content of the master alloy is selected such that the manganese content in the alloy to be produced within wide limits of 0.3 to 1 wt.% Can be adjusted taking into account the burnup in the base alloy.
- the strontium content of the master alloy is selected so that the strontium content in the alloy to be produced is 50-300, preferably 150-250 ppm.
- the die cast alloy thus produced has the same properties as the commercial AlSi9MgMnSr die cast alloys. It is at least equivalent to commercially available AlSi9MgMnSr die-cast alloys both in terms of joining technology and in terms of their dynamic and static properties.
- the method according to the invention it is possible to economically convert a commercially available base alloy into a high-quality die casting variant without accepting metallurgical problems.
- the die-cast alloy produced by the process according to the invention can be used particularly well in motor vehicle and engine construction.
