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: An attachment device for mounting a bumper cross-beam having a vertical front wall and a vertical rear wall spaced apart by a transverse wall onto a vehicle structure, the attachment device having a first end to be fixed to the vehicle structure and a second end configured to be attached to the bumper cross-beam, the attachment device being made from a hollow section profile, the periphery of which includes opposite side walls and substantially parallel opposite outer walls; the second end includes a flange, which can extend substantially beyond the vertical front wall after mounting the bumper cross beam, and on which a component is attached to the flange in front of said vertical front wall.
