Title (EN) ALUMINUM ALLOY PLATE WITH EXCELLENT FORMABILITY AND WELDABILITY FOR CELL CASE
(FR) PLAQUE D'ALLIAGE D'ALUMINIUM AYANT UNE EXCELLENTE APTITUDE AU FORMAGE ET AU SOUDAGE POUR BOÎTIER DE CELLULE
(JA) 成形性、溶接性に優れた電池ケース用アルミニウム合金板
Abstract:
(EN) There is provided a 1000-series aluminum alloy plate having high strength suitable for use in a large lithium-ion cell container and demonstrating excellent formability and laser weldability. The aluminum alloy plate contains 0.01-0.4 mass% of Si, 0.01-0.5 mass% of Fe, and 0.003-0.5 mass% of Co, the remainder consisting of Al and unavoidable impurities, and has a metal structure in which the number of second phase particles having a circular equivalent diameter of 3 µm or greater is less than 100 particles per mm2. A cold-rolled annealed plate of the aluminum alloy exhibits an elongation value of 30% or greater.
(FR) La présente invention concerne une plaque d'alliage d'aluminium série 1000 ayant une résistance élevée adaptée pour utilisation dans un grand conteneur de cellule lithium-ion et présentant une excellente aptitude au formage et au soudage laser. La plaque d'alliage d'aluminium contient de 0,01 à 0,4 % en masse de Si, de 0,01 à 0,5 % en masse de Fe, et de 0,003 à 0,5 % en masse de Co, le reste étant constitué de Al et des impuretés inévitables, et a une structure métallique dans laquelle le nombre de particules de deuxième phase ayant un diamètre équivalent circulaire de 3 µm ou plus est inférieur à 100 particules par mm2. Une plaque recuite laminée à froid de l'alliage d'aluminium présente une valeur d'allongement de 30 % ou plus.
(JA)  大型リチウムイオン電池容器に適用可能な高強度を有しており、しかも成形性にも優れ、さらにレーザー溶接性にも優れた1000系アルミニウム合金板を提供する。Si:0.01~0.4質量%、Fe:0.01~0.5質量%、Co:0.003~0.5質量%を含有し、残部Alおよび不可避的不純物からなり、円相当径3μm以上の第2相粒子数が100個/mm未満である金属組織を有するアルミニウム合金板。 その冷延焼鈍板は、30%以上の伸びの値を呈する。
