Abstract

L’invention concerne un procédé de fabrication d’une tôle d’épaisseur finale comprise entre 6 et 50 mm comprenant des étapes de coulée d’ une plaque de laminage en alliage d’aluminium de composition, en % en poids, Si : 0,6 – 1,3 ; Mg : 0,6 – 1,2 ; Mn : 0,65 – 1,0 ; Fe : 0,04 – 0,20 ; Cr ≤ 0,05 ; Ti ≤ 0,15 ; Cu ≤ 0,1; autres éléments < 0,05 chacun et < 0,15 au total, reste aluminium, homogénéisation, laminage à chaud, laminage à froid, mise en solution, trempe détensionnement par traction contrôlée et revenu. Les produits obtenus par le procédé selon l’invention sont particulièrement utiles pour la réalisation d'éléments de chambres à vide car ils présentent des caractéristiques mécaniques suffisantes, une stabilité dimensionnelle améliorée pour les étapes d’usinage ainsi qu'une aptitude optimale à la création de couches d'oxydes avec résistance chimique élevée
