Title
(EN) ALUMINUM ALLOY CLADDING MATERIAL
(FR) MATÉRIAU DE REVÊTEMENT EN ALLIAGE D'ALUMINIUM
(JA) アルミニウム合金クラッド材
Abstract
(EN) This aluminum alloy cladding material has a sacrificial material disposed on both surfaces of a core material. The composition of the core material contains, in terms of mass%, 0.7-1.8% of Mn, 0.3-1.3% of Si, 0.05-0.7% of Fe and 0.5-3.0% of Zn, with the remainder comprising Al and unavoidable impurities. The composition of the sacrificial material contains, in terms of mass%, 0.005-0.7% of Mn, 0.05-0.3% of Fe and 1.0-4.0% of Zn, with the remainder comprising Al and unavoidable impurities. The Zn content in the sacrificial material is at least 0.2 mass% higher than the Zn content in the core material. The potential of the core material after a brazing heat treatment is -700 to 870 mV.
(FR) Ce matériau de revêtement en alliage d'aluminium comporte un matériau sacrificiel disposé sur les deux surfaces d'un matériau d'âme. La composition du matériau d'âme contient, en termes de pourcentage en masse, 0,7 à 1,8 % de Mn, 0,3 à 1,3 % de Si, 0,05 à 0,7 % de Fe et 0,5 à 3,0 % de Zn, le reste comprenant de l'Al et les inévitables impuretés. La composition du matériau sacrificiel contient, en termes de pourcentage en masse, 0,005 à 7,0 % de Mn, 0,05 à 0,3 % de Fe et 1,0 à 4,0 % de Zn, le reste comprenant de l'Al et les inévitables impuretés. La teneur en Zn dans le matériau sacrificiel est supérieur d'au moins 0,2 % en masse à la teneur en Zn dans le matériau d'âme. Le potentiel du matériau d'âme après un traitement thermique de brasage est de 700 à 870 mV.
