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 cast pieces to manufacture with high quality requirements.
  • the quality of a die casting depends not only on the machine setting and the chosen method, but also to a large extent on the chemical composition and structure the cast alloy used. These two latter parameters are known to influence the pourability, the feeding behavior (G. Schindelbauer, J. Czikel '' Mold Fill Capacity and Volume Deficit of Common Aluminum Die Cast Alloys '' Foundry Research 42, 1990, pp. 88/89), the mechanical Properties and - particularly important in 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).
  • AlMg alloys are also known which are distinguished by a high ductility. Such an alloy is disclosed, for example, in US-A-5 573 606. However, these alloys have the disadvantage of high mold wear and cause molding problems, which significantly reduces productivity.
  • the alloy should also be easy to weld, a high corrosion resistance and in particular show no susceptibility to stress corrosion cracking.
  • 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 manganese content prevents sticking in the mold and ensures good mold release.
  • the magnesium content in combination with manganese gives the casting a high level of design stability, so that very little or no distortion can be expected even when demoulded.
  • this alloy can also be used for Use thixocasting or thixo forging.
  • the ⁇ phase forms when it melts again immediately, so that excellent thixotropic properties are available.
  • a grain size of ⁇ 100 ⁇ m is generated at the usual heating speeds.
  • the tendency of the casting to stick in the mold can be drastically reduced and the forming behavior can be significantly improved if manganese partially through Cer is replaced.
  • the alloy therefore preferably contains 0.05 to 0.80% by weight, in particular 0.10 to 0.50% by weight of cerium. An optimal effect is achieved if the sum of the cerium and manganese contents in the alloy is at least 0.80% by weight is and the alloy contains at least 0.4 wt .-% manganese.
  • a special embodiment of the aluminum casting alloy according to the invention is seen in the fact that the alloy is already in the rheological structure and is particularly suitable for thixocasting or thixo forging.
  • alloy is easy to weld, shows excellent casting behavior, a practically negligible tendency to stick and can be shaped well.
