A population of extrusion billets has a specification such that every billet is of an alloy of composition (in wt.%): Fe <0.35; Si 0.20-0.6; Mn <0.10; Mg 0.25-0.9; Cu <0.015; Ti <0.10; Cr <0.10; Zn <0.03; balance Al of commercial purity. After ageing to T5 or T6 temper, extruded sections can be etched and anodised to give extruded matt anodised sections having improved properties.

L'invention concerne une population de billettes d'extrusion qui a une spécification telle que chaque billette est constituée d'un alliage qui a la composition suivante (en % en poids): Fe est inférieur à 0,35; Si varie de 0,20 à 0,6; Mn est inférieur à 0,10; Mg varie de 0,25 à 0,9; Cu est inférieur à 0,015; Ti est inférieur à 0,10; Cr est inférieur à 0,10; Zn est inférieur à 0,03; le reste étant un Al de pureté commerciale. Après vieillissement par revenu de type T5 ou T6, des sections extrudées peuvent être attaquées et anodisées de façon à former des sections anodisées de matte extrudée qui ont des propriétés améliorées.
