Definitions

• the invention relates to an aluminum casting alloy.
• the invention is based on the task of making available an improved Al casting alloy, in particular a high-strength die-casting alloy, which demonstrates improved castability.
• the Al casting alloy according to the invention contains at least five of the following alloy components:
• alloy components according to the invention leads to a significant improvement in castability and in the mechanical properties, which is already found in the casting state, but, in particular, in the case of a cast component, after two hours of heat treatment, namely solution annealing and subsequent aging, wherein quenching of the cast component in water is preferably provided between these two heat treatment stages.
• heat treatment namely solution annealing and subsequent aging
• quenching of the cast component in water is preferably provided between these two heat treatment stages.
• wheel-controlling components very preferably for damping supports, wheel mounts and, in particular, pivot bearings, but also for control arms or transverse subframes, in particular integral subframes, higher mechanical characteristic values are obtained in this manner.
• Mg is contained at a content of maximally or of less than 0.8 wt.-%, preferably of maximally or of less than 0.75 wt.-%, particularly preferably of maximally or of less than 0.7 wt.-%, very particularly preferably of maximally or of less than 0.65 wt.-%, even more preferably of maximally or of less than 0.60 wt.-%, even more preferably of maximally or of less than 0.55 wt.-%, even more preferably of maximally or of less than 0.50 wt.-%.
• Fe is contained at a content of at least or of more than 0.05 wt.-%, preferably of at least or of more than 0.07 wt.-%, particularly preferably of at least or of more than 0.09 wt.-%, very particularly preferably of at least or of more than 0.11 wt.-%, even more preferably of at least or of more than 0.13 wt.-%, even more preferably of at least or of more than 0.15 wt.-%.
