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.

Manufacturing process for obtaining high strength solid extruded products made from 6XXX aluminium alloys for towing eye

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.
