The mechanical properties of a die casting component made of an aluminium alloy have the following proportions; magnesium 3.0-6.0 wt %, silicon 1.4-3.5 wt % manganese 0.5-2.0 wt %, iron max. 0.15 wt %, titanium max. 0.2 wt %, the remainder being aluminium and other components having a total proportion of a maximum of 0.2 wt %. Said mechanical properties improve significantly by virtue of the fact that the die casting component is subjected to heat treatment in the form of thermal hardening at a temperature T of 180° C.=T=320° C. over a period of at least thirty minutes after die casting.
