Abstract (en)

[origin: EP0933441A1] A die cast component of precipitation hardenable aluminum-magnesium-silicon alloy is subjected to a heterogenization anneal to increase its ductility. In the production of a component of Mg2Si precipitation hardenable aluminum alloy with a Si or Mg2Si eutectic by die casting, the die cast component is subjected to a heterogenization anneal at 320-410 degrees C for 320-10 min. Preferred Features: The aluminum alloy contains 2.0-11.0 wt.% Si and 0.10-5.5 wt.% Mg, with optional additions of 0.1-0.5 wt.% Fe and 0.2-1.2 wt.% Mn.
