Abstract
L'invention concerne un produit extrudé et brasé présentant une résistance à la corrosion améliorée grâce à une faible formation de grains grossiers recristallisés, ainsi qu'un procédé de fabrication de celui-ci. Le produit extrudé et brasé comprend un alliage d'aluminium comprenant en pourcentage en poids : Mn 0,6-0,75 ; Fe 0,11-0,16 ; Si 0,10-0,19 ; Cu < 0,01 ; Zn < 0,05 ; Ti < 0,05 ; éventuellement un agent d'affinage du grain ; éventuellement Ni < 0,01 ; et le reste étant constitué d'aluminium et des inévitables impuretés.
