Abstract (en)
[origin: EP2072628A1] The present invention relates to an AlMgSi-type aluminium alloy extruded or forged product having a high impact resistance, the aluminium alloy comprising, in wt.%: Si 0.5 to 0.95, Mg 0.6 to 0.95, Mn 0.1 to 0.3, V 0.05 to 0.25, Ni 0.05 to 0.25, Cu maximum 0.3,optionally one or two element(s) selected from the group consisting of: (Cr 0.05 to 0.2, and Zr 0.05 to 0.2), Zn< 0.2, Fe < 0.5, Ti < 0.1, inevitable impurities and balance aluminium. The invention further relates to a crash box made from such aluminium alloy.
