Abstract (en)
[origin: EP2471967A1] The present invention relates to iron containing aluminium alloys free of primary platelet-shaped beta-phase of the Al 5 FeSi-type in the solidified structure presenting the following chemical composition (in weight %): Si: 6.00 - 9.50; Fe: 0.15 - 0.60; Mn: 0.04 - 0.60; Mg: 0.20 - 0.70; Cr:0.01 - 0.60; Ti: 0.05 - 0.30; Sr and/or Na: 0.001 - 0.25; V:0.00 - 0.60; Cu:0.01 - 0.25; Ni: 0.01 - 0.1; Zn: 0.01 - 0.1; the balance being Al and incidental impurities. The present invention relates also to a process for the preparation of this aluminium alloy and aluminium alloy casting for example as components in aeronautic, automotive and energy industry.
