Abstract: The invention relates to a manufacturing process for obtaining 6xxx-series aluminium alloy solid extruded products, comprising Si: 0.3-1.7 wt. %; Mg: 0.1-1.4 wt. %, Cu: 0.1-0.8 wt. %, Zn 0.005-0.7 wt %, one or more dispersoid element, from the group consisting of Mn 0.15-1 wt. %, Cr 0.05-0.4 wt. % and Zr 0.05-0.25 wt. %, Fe at most 0.5 wt. %, other elements at most 0.05 wt. % the rest being aluminium, having particularly high mechanical properties, typically an ultimate tensile strength higher than 400 MPa, preferably 430 MPa, and more preferably 450 MPa without the need for a post-extrusion solution heat treatment operation. The invention also concerns a manufacturing process for obtaining a bumper system in which is integrated a towing eye, said towing eye being made with said high mechanical properties aluminium alloys.

Abstract: The invention relates to a bumper (10) for a motor vehicle, with a crossmember element (20) which has preferably two homogeneous outer sections (12, 13) and a central section (11) differing from the outer sections (12, 13), wherein the central section (11) is displaced vertically downwards or upwards with respect to the two outer sections (12, 13). According to the invention, provision is made that the crossmember element (20) is constructed as an extrusion and in that at least one of the sections (11 to 13) has at least one additional element (35, 38, 39) arranged monolithically with the crossmember element (20).

Abstract: A method for producing a metallic formed hollow profile which is curved in at least one axis, in which a hollow metallic profile element is formed by means of two tool elements of a tool group which hold a cross section part of the hollow metallic profile element, on a length of the hollow metallic profile element, wherein at least two tool groups each having two tool elements which are spaced from one another are provided, wherein each of the tool groups is fixed to the hollow metallic profile element at least in regions in a forced based manner, wherein the region of the hollow metallic profile element to be formed is arranged between the tool groups, and wherein through relative movement of the tool groups to one another, the hollow metallic profile element in the freely arranged region located between the tool groups is formed at least partially.
