Title (EN) ROLLED ALUMINIUM ALLOY FOR HEAT EXCHANGERS
(FR) ALLIAGE EN ALUMINIUM LAMINÉ POUR ÉCHANGEURS DE CHALEUR
Abstract:
(EN) The invention relates to a heat exchanger incorporating at least one component made from a rolled 6xxx-series aluminium alloy having a composition, in wt.%, of Si 0.2% to 1.3%, Mg 0.3% to 1.3%, Cu up to 0.80%, Fe 0.05% to 1.0%, Mn 0.05% to 0.70%, optionally one or two elements selected from the group 0.05-0.35% Zr and 0.04-0.35% Cr, Zn up to 0.25%, Ti up to 0.25%, balance unavoidable impurities and aluminium, and wherein the Fe/Mn ratio is <1.90.
(FR) L'invention concerne un échangeur de chaleur comprenant au moins un composant fabriqué à partir d'un alliage en aluminium laminé de la série 6xxx ayant une composition, en % en poids, de 0,2 % à 1,3 % de Si, 0,3 % à 1,3 % de Mg, jusqu'à 0,80 % de Cu, 0,05 % à 1,0 % de Fe, de 0,05 % à 0,70 % de Mn, éventuellement un ou deux éléments choisis dans le groupe de 0,05 à 0,35 % de Zr et de 0,04 à 0,35 % de Cr, jusqu'à 0,25 % de Zn, jusqu'à 0,25 % de Ti, le reste étant des impuretés inévitables et de l'aluminium, et le rapport Fe/Mn étant < 1,90.
