Definitions

  • the invention relates to an aluminum alloy for die casting components with high elongation in the as-cast state.
  • Die casting technology has developed so far today that it is possible Manufacture components with high quality standards.
  • the quality of a die cast part depends not only on the machine setting and the selected one Process, but also to a large extent on the chemical composition and the structure of the aluminum alloy used. These last two parameters are known to influence the Pourability, the feeding behavior (G. Schindelbauer, J. Czikel “Mold filling capacity and volume deficit of common aluminum die casting alloys ", Giessereiforschung 42, 1990, pp. 88/89), the mechanical properties and - particularly important for die casting - the service life the casting tools (L.A. Norström, B. Klarenfjord, M. Svenson "General Aspects on Wash-out Mechanism in Aluminum Diecasting Dies ", 17th International NADCA Diecasting Congress 1993, Cleveland OH).
  • the die-cast parts usually have to be achieved be subjected to a heat treatment.
  • This heat treatment is for molding the casting phases and thus achieving a tough Breaking behavior necessary.
  • Heat treatment usually means one Solution annealing at temperatures just below the solidus temperature subsequent quenching in water or other medium to temperatures ⁇ 100 ° C.
  • the material treated in this way now has a low proof stress and tensile strength. To get these properties to the one you want Warming is then carried out to increase the value.
  • This can also be process-related, e.g. through a thermal load when painting or by relaxing annealing an entire component group.
  • EP-A-0 687 742 An AlSi alloy with good mechanical properties in the as-cast state is out EP-A-0 687 742. Also are, for example, from EP-A-0 911 420 Alloys of the AIMg type are known which have a very high ductility when cast have, but with complicated shape design to warm or cold cracks tend and are therefore unsuitable. Another disadvantage of ductile die casting alloys is their slow aging in the as-cast state, which is a temporal Change in mechanical properties - including a loss of stretch - can result. This behavior is tolerated in many applications since the property limits are not exceeded or fallen short of, not tolerable in some applications and can only be achieved through targeted heat treatment turned off.
  • the invention has for its object a suitable for die casting To provide aluminum alloy that is very easy to cast, in the as-cast state has a high elongation and does not age after casting. About that In addition, the alloy should be easy to weld and flare, riveted can and have a high corrosion resistance.
  • the object is achieved with an aluminum alloy 8.5 to 10.5% by weight silicon 0.3 to 0.8 wt% manganese Max. 0.06 wt% magnesium Max. 0.15 wt% iron Max. 0.03 wt% copper Max. 0.10 wt% zinc Max.
  • the stretch can be improved even further.
  • the preferred salary is at 0.15 to 0.20% by weight Zr.
  • the relatively large proportion of eutectic silicon is refined by strontium. Compared to granular die-cast alloys with higher impurities the alloy according to the invention also has advantages in terms of fatigue strength.
  • the fracture toughness is due to the very small presence Mixed crystals and the refined eutectic are higher.
  • the strontium content is preferably between 50 and 150 ppm and generally should not be below 50 ppm drop, otherwise the casting behavior can be impaired. Instead of of strontium sodium and / or calcium can be added.
  • the limitation of the magnesium content to preferably max. 0.05% by weight Mg has the effect that the eutectic structure and the alloy are not coarsened has no curing potential, which contributes to high elongation.
  • the proportion of manganese prevents sticking in the mold and one good demoldability guaranteed.
  • the manganese content gives the casting one high dimensional stability at elevated temperature, so that when demolding with very little to no delay is to be expected.
  • the alloy according to the invention can be riveted in the as-cast state.
  • the alloy according to the invention is preferably used as a horizontal continuous casting mass manufactured. It can be used without complex melt cleaning Die casting alloy with low oxide contamination are melted: one important prerequisite for achieving high elongation values in the die-cast part.
  • AlSi alloy When melting, any contamination of the melt, especially through Avoid copper or iron.
  • the cleaning of the permanently refined according to the invention AlSi alloy is preferably carried out by means of a purge gas treatment with inert gases using an impeller.
  • Grain refinement is preferably carried out in the alloy according to the invention.
  • the alloy can be gallium phosphide and / or indium phosphide in an amount corresponding to 1 to 250 ppm, preferably 1 to 30 ppm phosphorus are fed.
  • the alloy can be used for grain refinement also contain titanium and boron, with the addition of titanium and boron over a master alloy with 1 to 2% by weight of Ti and 1 to 2% by weight of B, the rest being aluminum, he follows.
  • the aluminum master alloy preferably contains 1.3 to 1.8% by weight of Ti and 1.3 to 1.8 wt% B and has a Ti / B weight ratio of about 0.8 up 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 aluminum alloy according to the invention is particularly suitable for production of safety components in the die casting process.
