<p>The invention relates to a hollow profile formed by assembling at least a first solid profile (1) made of aluminium alloy with at least a second solid profile (2) made of aluminium alloy, said first and second profiles being obtained by extrusion and each having a yield strength of at least 350 MPa and preferably of at least 400 MPa. Typically at least one of said solid profiles is made of an aluminium alloy of the 2xxx, 6xxx or 7xxx series, and is preferably selected in the group comprising the 6082, 6056, 6013, 7108, 7020, 7022, 7075, 7349, 7449, 2017, 2014, 2196 and 2195 alloys. The hollow profiles of the invention are advantageously used for making rims of cycle wheels.</p> |
