Abstract (en)
[origin: FR2746414A1] An aluminium alloy suitable for thixotropic shaping, comprising 5-7.2 wt % of Si, 1-5 wt % of Cu, < 1 wt % of Mg, < 3 wt % of Zn, < 1.5 wt % of Fe, and < 1 wt % each and < 3 wt % in all of other elements, with the proviso that % Si < 7.5 - % Cu/3, and including no non-remelted polyhedral silicon crystals when it is reheated in a semi-solid state to give a liquid fraction level of 35-55 %, is disclosed. The resulting parts produced by thixotropic shaping by means of said alloy have high mechanical strength and good elongation properties.
