Abstract

An alloy of the AlMgSi type which is suited for producing structural components which are highly capable of absorbing kinetic energy by means of plastic deformation contains silicon provided in a wt. % ranging from 0.45 to 0.85, magnesium in a wt. % ranging from 0.35 to 1.0, copper in a wt. % ranging from 0.05 to 0.30, iron in a wt. % ranging from 0.05 to 0.25, vanadium in a maximum wt. % of 0.25, manganese in a maximum wt. % of 0.10, as well as impurities which result during production in a maximum wt. % of 0.05 individually and 0.15 in total, and aluminum as the remainder wt. %. The structural component is manufactured from a rolled strip or sheet of the alloy. Components made of this alloy are suited as safety parts used in the construction of vehicles. The alloy is also suited for producing vehicle body parts which comprise a high degree of flexibility without the occurrence of cracking and orange peel effects, in particular, for producing two-sheet structures such as an engine hood, door, and trunk lid of a passenger car. These structural components and vehicle body parts can be easily recycled together.
