Definitions

  • the invention relates to aluminium casting alloys, in particular for chassis applications.
  • Generally used for this purpose are primarily molten sub-eutectic AlSi alloys which are alloyed with low Mg contents, e.g. AlSi7Mg or AlSi11Mg, to increase the strength.
  • AlSi(Mg, Cu) alloys are also used but these can only have niche applications as a result of the corrosive properties.
  • AlCu(Ti, Mg) alloys which offer the highest strengths among the common alloys.
  • the AlMg alloys form niche applications in the chassis sector.
  • Other families of alloys such as AlZn or AlLi play no role in chassis.
  • the components made of the aforesaid alloys are usually subjected to a two-stage heat treatment to achieve the desired properties.
  • the object of the invention to develop an alloy having properties which still have sufficiently high breaking elongation values at high material strengths, particularly for applications in automobile construction.
  • This combination of properties is necessary, for example, in chassis applications in order to be able to withstand cases of abuse.
  • the alloy must be sufficiently pourable and should not impose any excessively high requirements on the melting process and the metal cycle on account of their composition.
  • Si 2.5 to 3.3, preferably 2.7 to 3.1 wt. %
  • Mg 0.2 to 0.7, preferably 0.3 to 0.6 wt. %
  • Fe ⁇ 0.18, preferably 0.05 to 0.16 wt. %
  • Mn ⁇ 0.5, preferably 0.05 to 0.4 wt. %
  • the alloys according to the invention have a strength-strain ratio which cannot be achieved with conventional Al casting alloys subject to the requirement of freedom from. Cu.
  • pressure-assisted casting methods e.g. low-pressure—back-pressure chill casting, better mechanical technological properties are obtained from the good casting structure.
  • the alloy is grain-refined.
  • Tempering 150 and 200° C. for 1 to 10 h.
  • the corrosion resistance is increased significantly.
  • the product is also relatively inexpensive because none of the alloying additions such as, for example, rare earth metals which make the product more expensive are used, the usual melting treatment can be used and no particular expenditure is required for separating circuits.
  • the pourability makes it possible to achieve a casting free from major defects, known as blow holes and secondly, the microstructure is positively influenced in such a manner that the number of internal notches which reduce the breaking elongation is kept as low as possible.
