Abstract

lorsqu'on utilise les alliages d'aluminium des séries AA3000 et AA1000 pour produire des produits extrudés destinés à des applications à échanges thermiques, il est possible d'obtenir une excellente résistance à la corrosion tant avant qu'après le cycle de brasage, par la maîtrise du niveau très bas du cuivre et du nickel utilisé dans cet alliage. Pour obtenir ces résultats, le contenu en cuivre ne pas être supérieur à 0,006 % en masse et celui du nickel ne doit pas dépasser 0,005 % en masse. Un alliage typique de l'invention contient en masse d'environ 0,001 % à 0,5 % de manganèse, 0,001 % à 0,7 % de fer, 0,001 % à 0,02 % de titane, 0,001 % à 0,3 % de silice, moins de 0,006 % de cuivre, moins de 0,005 % de nickel et de 0,001 % à 0,02 % de zinc, le solde étant constitué d'aluminium et d'impuretés incidentes. Aucune adjonction de zinc n'est requise, que ce soit par pulvérisation ou par adjonction.
