Definitions

  • the invention relates to an aluminum casting alloy, in particular an aluminum die casting alloy.
  • Die casting technology has developed so far today that it is possible to produce castings with high quality standards.
  • the quality of a die-cast piece depends not only on the machine setting and the method chosen, but also to a large extent on the chemical composition and structure of the casting alloy used. These two last-mentioned parameters are known to influence the castability, the feeding behavior (G. Schindelbauer, J. Czikel "Mold filling capacity and volume deficit of common aluminum die-cast alloys" Giessereiforutz 42, 1990, p. 88/89), the mechanical properties and - Particularly important in die casting - the service life of the casting tools (LA Norström, B. Klarenfjord, M. Svenson "General Aspects on Wash-out Mechanism in Alumium Diecasting Dies", 17th International NADCADiecastingcongress 1993, Cleveland OH).
  • the castings are subjected to a heat treatment.
  • This heat treatment is necessary for molding the casting phases and thus for achieving tough fracture behavior.
  • Heat treatment usually means solution annealing at temperatures just below the target temperature with subsequent quenching in water or another medium to temperatures ⁇ 100 ⁇ C.
  • the material treated in this way now has a low yield strength and tensile strength.
  • a warm aging is then carried out. This can also be done depending on the process, for example by thermal exposure during painting or by the relaxation annealing of the entire component group.
  • the degree of purity of the aluminum used to manufacture the alloy corresponds to that of aluminum A199.8H.
  • This alloy has a well molded ⁇ phase in the as-cast state.
  • the eutectic mainly consisting of Mg_Si and Al ß Mn phases, is very fine and therefore leads to a highly ductile fracture behavior.
  • the eutectic portion of about 30% ensures excellent pourability.
  • the manganese content prevents sticking in the mold and ensures good mold release.
  • the magnesium content in connection with manganese gives the cast piece a high level of design strength, so that very little or no distortion can be expected even when it is removed from the mold.
  • this alloy can be used excellently for thixocasting or thixo forging.
  • the ⁇ phase forms immediately when it melts again, so that excellent thixotropic properties are present.
  • a grain size of ⁇ 100 ⁇ m is generated at the usual heating speeds.
  • a preferred alloy composition has
  • Another preferred alloy composition has
  • a particular embodiment of the aluminum cast embedding according to the invention is seen in the fact that the alloy is already in the rheological structure and is therefore particularly suitable for thixocasting or thixo forging.
  • the aluminum casting alloy according to the invention is intended in particular for processing in die casting, it can of course also be cast using other methods, e.g.
  • the alloy is heat-treatable, weldable and shows excellent casting behavior.
  • a preferred use of the aluminum casting alloy according to the invention is in die casting for components with high demands on the mechanical properties, without the need for heat treatment.
