Susceptibility to crack initiation and crack propagation e.g. of oxides or primary phases and the TMF-HCF lifetime is reduced by the choice of the alloy according to the invention over the previously known production methods of pistons and similar engine components.

The diffusion of aluminum and magnesium can also be prevented. The above effects are particularly relevant when using holding furnaces.
- a fine / thin oxide layer is formed on the solidification front during casting, for example, in a mold, which improves flowability. Overall, thus thin walls and fine mold structures can be filled better and without additional assistance.
- the addition of beryllium improves the strength characteristics of the alloy as a whole. During aging, a higher density of strength enhancing precipitates is achievable.

- Alloy D is advantageous in that the addition of beryllium, as described above, improves the oxidation and flow behavior of the melt as well as the strength of the alloy. This effect is further increased by the comparatively low Mg content and the limited to a low level Ca content. Alloy D may also have the alloying elements in the following preferred concentration ranges: nickel (Ni) from about 2 to about 3.5 wt%, copper (Cu) from about 3.7 to about 5.2 wt%.

- the aluminum alloy contains at most five parts iron versus one part manganese, preferably about 2.5 parts iron versus one part manganese.

- a low content of pores is preferably to be understood as meaning a porosity of ⁇ 0.01% and less than a few primary silicon ⁇ 1%.
- the fine microstructure is advantageously described by the fact that the average length of the primary silicon about ⁇ 5 ⁇ and its maximum length is about ⁇ 10 ⁇ and the intermetallic phases and / or primary precipitates lengths of on average about ⁇ 30 ⁇ and maximum ⁇ 50 pm.
- the fine microstructure contributes in particular to the improvement of the thermomechanical fatigue strength. Limiting the size of the primary phases can reduce the susceptibility to crack initiation and crack propagation and thus significantly increase the TMF-HCF lifetime. Furthermore, it is particularly advantageous due to the notch effect of pores and inclusions to keep their content low.
