Title
(EN) ALUMINUM ALLOY PLATE FOR CAN BODY AND PRODUCTION METHOD THEREFOR
(FR) PLAQUE D’ALLIAGE D’ALUMINIUM POUR CORPS DE BOÎTE ET PROCÉDÉ DE PRODUCTION DE CELLE-CI
(JA) 缶ボディ用アルミニウム合金板及びその製造方法
Abstract
(EN) Provided is an aluminum alloy plate for a can body having a chemical composition that includes, in mass%, 1.0-1.5% of Mg, 0.8-1.2% of Mn, 0.20-0.30% of Cu, 0.25-0.60% of Fe, 0.20-0.40% of Si, and a remainder of Al and unavoidable impurities, and that has a conductivity of 37.0-40.0% IACS. The aluminum alloy plate for a can body is produced through a plurality of cold-rolling passes, and the tensile strength σB(10) and yield strength σ0.2(10) when the material is aged for ten hours at a temperature of 150 °C directly before the final cold-rolling pass and the tensile strength σB(1) and yield strength σ0.2(1) when the material is aged for one hour at a temperature of 150 °C directly before the final cold-rolling pass satisfy the relationships σB(10) - σB(1) ≥ 5 (Mpa) and σ0.2(10) - σ0.2(1) ≥ 1 (Mpa).
(FR) La présente invention concerne une plaque d’alliage d’aluminium pour un corps de boîte ayant une composition chimique qui comprend, en % en masse, 1,0 à 1,5 % de Mg, 0,8 à 1,2 % de Mn, 0,20 à 0,30 % de Cu, 0,25 à 0,60 % de Fe, 0,20 à 0,40 % de Si, et le résidu de Al et les impuretés inévitables, et qui a une conductivité de 37,0 à 40,0 % IACS. La plaque d’alliage d’aluminium pour un corps de boîte est produite par une pluralité d’opérations de laminage à froid, et la résistance à la traction σB(10) et la limite d’élasticité σ0,2(10) lorsque le matériau est vieilli pendant dix heures à une température de 150 °C juste avant l’opération de laminage à froid finale et la résistance à la traction σB(1) et la limite d’élasticité σ0,2(1) lorsque le matériau est vieilli pendant une heure à une température de 150 °C directement avant l’opération de laminage à froid finale satisfont aux relations σB(10) - σB(1) ≥ 5 (Mpa) et 0,2(10) - σ0.2(1) ≥ 1 (Mpa).
(JA)  Mg:1.0~1.5%(質量%、以下同様)、Mn:0.8~1.2%、Cu:0.20~0.30%、Fe:0.25~0.60%、Si:0.20~0.40%を含有し、残部がAl及び不可避不純物からなる化学成分を有し、導電率が37.0~40.0%IACSである缶ボディ用アルミニウム合金板である。また、缶ボディ用アルミニウム合金板は、複数回パスの冷間圧延を経て製造されており、冷間圧延の最終パス直前における材料を150℃の温度で10時間時効処理したときの引張強さσB(10)及び耐力σ0.2(10)と、150℃の温度で1時間時効処理したときの引張強さσB(1)及び耐力σ0.2(1)とが、 σB(10)-σB(1)≧5(MPa)、σ0.2(10)-σ0.2(1)≧1(MPa) の関係を満たしている。
