Abstract

L'invention concerne un procédé de production d'une feuille en alliage d'aluminium dotée d'une excellente aptitude au pliage, ledit procédé étant utilisé dans la formation de panneaux pour automobiles. Cet alliage d'aluminium renferme entre 0,5 et 0,75 % en poids de Mg, entre 0,7 et 0,85 % en poids de Si, entre 0,15 et 0,35 % en poids de Mn, entre 0,1 et 0,3 % en poids de Fe, facultativement entre 0,2 et 0,4 % en poids de Cu, le reste d'Al et des impuretés diverses. On coule de manière semi-continue cet alliage en lingots. On soumet lesdits lingots à un laminage à chaud ou à froid, puis on les traite thermiquement dans une solution. On vieillit préalablement cette matière de feuille en la refroidissant rapidement d'une température initiale d'au moins 80 ·C à température ambiante, avec un taux de refroidissement de plus de 5 ·C par heure.
