Definitions

  • the invention relates to the use of an aluminum alloy for die casting, for thixocasting or thixo forging.
  • Die casting technology has developed so far today that it is possible to make castings with high quality standards to manufacture.
  • the quality of a die-cast piece depends but not only on the machine setting and the selected one Process, but also to a large extent from the chemical Composition and structure of the used Cast alloy. These two latter 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 " Foundry Research 42, 1990, pp. 88/89), the mechanical properties and - especially in die casting important - the service life of 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).
  • This Heat treatment is for molding the casting phases and necessary to achieve tough fracture behavior.
  • Heat treatment usually means solution annealing at temperatures just below the solidus temperature with subsequent quenching in water or another Medium at temperatures ⁇ 100 ° C.
  • the material treated in this way now has a low yield strength and tensile strength.
  • heat aging is carried out. This can also take place due to the process, e.g. through a thermal Exposure when painting or by relaxation annealing an entire component group.
  • JP-A-1149938 is a die casting alloy with 3 to 6% Mg, 0.3 to 2.5% Si, 0 to 2% Mn, 0.03 to 0.40% Ti and optionally 0.001 to 0.01% Be and Al are known as the remainder.
  • An example Alloy mentioned has the following composition with regard to their main alloying elements: 5% Mg-2.2% Si 0.4% Mn.
  • DE-B-1758441 describes an Al cast alloy with 0.6 to 1.2% Mn, 4.5 to 7.5% Mg, 0.8 to 2.5% Si, 0.1 to 0.3% Ti and 0.2 to 1.0% Cu disclosed.
  • GB-A-1384264 describes an aluminum casting alloy with 3.5 to 7% Mg, 0.8 to 2.5% Si and 0.6 to 1.8% Mn.
  • This alloy has a well molded ⁇ phase in the as-cast state.
  • the eutectic mainly consisting of Mg 2 Si and Al 6 Mn phases, is very fine and therefore leads to a highly ductile fracture behavior.
  • the eutectic content of around 30% ensures excellent castability.
  • the manganese content prevents sticking in the mold and ensures good mold release.
  • the magnesium content in connection with manganese gives the casting a high level of design stability, so that very little or no distortion can be expected even when demolding.
  • the alloy is heat treatable, weldable and shows excellent casting behavior.
  • a preferred application the aluminum alloy according to the invention is in die casting for components with high mechanical requirements Properties without the need for heat treatment is required.
