Aluminium alloy and aluminium alloy strip for pedestrian impact protection

Abstract

Embodiments of an aluminium alloy for vehicle applications, an aluminium alloy strip, and a sheet metal body part of a motor vehicle manufactured from the aluminium alloy strip are disclosed herein. The object to provide an aluminium alloy for vehicle applications, which can be processed into a strip using conventional method steps such that the manufactured strip, with a moderate level of strength, exhibits only a low tendency to hardening from the T4 condition and a use in the area of pedestrian impact protection is possible, is achieved in that the aluminium alloy has the following alloy constituents in percent by weight 0.40-0.55 wt % Si, 0.15-0.25 wt % Fe, 0-0.06 wt % Cu, 0.15-0.4 wt % Mn, 0.33-0.4 wt % Mg, 0-0.03 wt % Cr, 0.01-0.10 wt % Ti, and the remainder being Al and unavoidable impurities, individually at most 0.05 wt %, in total at most 0.15 wt %.
