Definitions
- the invention relates to aluminum casting alloys, in particular for chassis applications.
- AISi alloys are used, which are alloyed with low levels of Mg for strength enhancement, e.g. AISi7Mg or AISiHMg.
- Mg for strength enhancement
- AISi (Mg, Cu) alloys are also used, but because of their corrosive properties they can only find niche applications.
- AICu (Ti, Mg) alloys which offer the highest strengths among common alloys.
- niche applications in the chassis area are the AlMg alloys.
- Other alloy families, such as AIZn or AILi play no role in the chassis.
- the components made from the above alloys are subjected to a two-stage heat treatment to obtain the desired properties.
- the existing alloy families have the disadvantage that only a limited strength-strain ratio can be achieved.
- the above-mentioned high-strength alloys with Cu addition are often eliminated due to the corrosive properties.
- AlMg alloys are significantly heavier castable and therefore limited in application (component geometry).
- the object of the invention was to develop an alloy which has properties which still have sufficiently high elongation at fracture values, in particular for applications in the automotive industry, with high material strengths. This property combination is necessary, for example, in chassis applications in order to be able to survive abuse cases.
- the alloy has to be sufficiently castable and, owing to its composition, should not impose excessive demands on the melting process and the metal circulation.
- Al casting alloys contain at least five of the following alloy constituents:
- 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%
- production-related impurities for example Pb, Ni, Zn, etc.
- production-related impurities for example Pb, Ni, Zn, etc.
- the alloys according to the invention have a strength-strain ratio which can not be achieved with conventional Al casting alloys under the requirement of Cu freedom.
- pressure-assisted casting eg low pressure - counter pressure Kogillenguss - resulting from the good cast structure better mechanical technological properties.
- the alloy is grain-fined.
- T4 one-stage tempering treatment
