Definitions
- the invention relates to a die-casting alloy based on aluminum-silicon.
- a Japanese standard alloy AC4 A is known, which is made of Al, 8-10Si, max. 0.55 Fe, max. 0.25Cu, 0.3-0.6Mn, 0.3-0.6Mg, max. 0.2Ti, max. 0.25Zn known for sand and permanent mold casting.
- the inventor has set himself the task of providing an aluminum die-casting alloy which, with regard to its mechanical properties both in the cast state and after heat treatment, meets the requirements placed on safety components such as wheels of passenger cars, is easy to weld, and has high corrosion resistance .
- the alloy should be easy to cast.
- the die-casting alloy according to the invention thus corresponds to the AlSi9Mg type with a considerably reduced iron content and a strontium refinement of the AlSi eutectic. Because of the high elongation values both in the as-cast state and after heat treatment, the alloy is particularly suitable for the production of safety components.
- die-castings produced from the alloy according to the invention can be subjected to all heat treatments.
- the mechanical properties achieved with heat treatment depend to a large extent on the magnesium content. Therefore, this can be tolerated very closely in production.
- the magnesium content is tailored to the requirements of the die casting.
- the alloy contains manganese to improve formability.
- the relatively large proportion of eutectic silicon is refined by strontium.
- the alloy according to the invention also has advantages in terms of fatigue strength.
- the fracture toughness is higher due to the very small mixed crystals and the refined eutectic.
- the alloy according to the invention is preferably produced as a horizontal continuous casting mass. This makes it possible to melt a die-casting alloy with low oxide contamination without complex melt cleaning: an important prerequisite for achieving high elongation values in the die-casting.
- the permanently refined AlSiMg alloy according to the invention is preferably cleaned by means of a purge gas treatment with inert gases using an impeller.
- the strontium content is preferably between 50 and 150 ppm and should generally not fall below 50 ppm, since otherwise the casting behavior can be impaired.
- zirconium in addition, 0.05 to 0.3% by weight, in particular 0.15 to 0.20% by weight, of zirconium can be added to the invention.
- Grain refinement is preferably carried out in the alloy according to the invention.
- the alloy gallium phosphide and / or indium phosphide can be added in an amount corresponding to 1 to 250 ppm, preferably 1 to 30 ppm phosphorus.
- the alloy for grain refinement can also contain titanium and boron, the addition of titanium and boron being effected via a master alloy with 1 to 2% by weight of titanium and 1 to 2% by weight of boron, the rest being aluminum.
- the master alloy preferably contains 1.3 to 1.8% by weight of titanium and 1.3 to 1.8% by weight of boron and has a titanium / boron weight ratio of approximately 0.8 to 1.2.
- the content of the master alloy in the alloy according to the invention is preferably set to 0.05 to 0.5% by weight.
- the die-casting alloy according to the invention is highly suitable for die-casting safety components, in particular for die-casting vehicle wheels such as wheels for passenger cars.
- the mechanical properties of the alloy according to the invention are shown in the table below. The values have been determined on test bars made from plates with a wall thickness of 2 to 4 mm. The ranges shown show the performance of the alloy, whereby the magnesium content and wall thickness should be restricted accordingly.
- the alloy is characterized by very good castability, very good corrosion resistance and excellent weldability.
