Abstract:
Casting alloy of the AlMgSi type, comprising:Magnesium3.0 to 7.0wt. %Silicon1.7 to 3.0wt. %Manganese0.2 to 0.48wt. %Iron0.15 to 0.35wt. %Titaniumup to 0.2wt. % max. as desiredNi0.1 to 0.4wt %and balance aluminum and production related impurities, individually at most 0.02 wt. % and, in total at most 0.2 wt. %, wherein the magnesium and silicon are present in the alloy in a Mg:Si weight ratio of 1.7:1, corresponding to the composition of the quasi binary eutectic made up of the solid state phases Al and Mg2Si, whereby the deviation from the exact composition of the quasi-binary eutectic amounts to at most âˆ’0.5 to +0.3 wt. % for magnesium and âˆ’0.3 to +0.5 wt. % for silicon.
