Title (EN) ALUMINIUM ALLOY PLATE FOR CAN END AND PRODUCTION METHOD THEREFOR
(FR) PLAQUE D'ALLIAGE D'ALUMINIUM POUR COUVERCLE DE CANETTE ET PROCÉDÉ DE PRODUCTION S'Y RAPPORTANT
(JA) 缶エンド用アルミニウム合金板及びその製造方法
Abstract:
(EN) An aluminium alloy plate for a can end according to the present disclosure comprises: an aluminium alloy plate including 4.0–5.5 mass% of Mg, 0.20–0.50 mass% of Mn, 0.10–0.50 mass% of Fe, 0.03–0.30 mass% of Si and a no more than 0.20 mass% of Cu, and the remainder being composed of Al and unavoidable impurities; and an organic resin coating film covering both surfaces of the aluminium alloy plate. In this aluminium alloy plate for a can end, if the surfaces of the organic resin coating film covering one surface and the other surface of the aluminium alloy plate, respectively, are designated as a first surface and a second surface, the dynamic friction coefficient of the first surface and the second surface is 0.01–0.03, inclusive. There is a difference of no more than 20 MPa between the minimum and maximum values for proof stress in the 0° direction, 45° direction and 90° direction with respect to the rolling direction. The R(AVE) calculated from the Lankford value R0, the Lankford value R45, and the Lankford value R90 is no less than 0.5.
(FR) La présente invention concerne une plaque d'alliage d'aluminium pour un couvercle de canette, comprenant : une plaque d'alliage d'aluminium comprenant 4,0 à 5,5 % en masse de Mg, 0,20 à 0,50 % en masse de Mn, 0,10 à 0,50 % en masse de Fe, 0,03 à 0,30 % en masse de Si et pas plus de 0,20 % en masse de Cu, le reste étant composé d'Al et d'impuretés inévitables ; et un film de revêtement de résine organique recouvrant les deux surfaces de la plaque d'alliage d'aluminium. Dans cette plaque d'alliage d'aluminium pour un couvercle de canette, si les surfaces du film de revêtement de résine organique recouvrant une surface et l'autre surface de la plaque d'alliage d'aluminium, respectivement, sont appelées première surface et seconde surface, le coefficient de frottement dynamique de la première surface et de la seconde surface est de 0,01 à 0,03, bornes incluses. Il y a une différence de pas plus de 20 MPa entre les valeurs minimale et maximale pour la limite conventionnelle d'élasticité dans la direction de 0°, la direction de 45° et la direction de 90° par rapport à la direction de laminage. Le coefficient R (AVE) calculé à partir de la valeur de coefficient de Lankford R0, de la valeur de coefficient de Lankford R45 et de la valeur de coefficient de Lankford R90 est inférieur ou égal à 0,5.
(JA) 本開示の缶エンド用アルミニウム合金板は、Mg:4.0~5.5質量%、Mn:0.20~0.50質量%、Fe:0.10~0.50質量%、Si:0.03~0.30質量%、及びCu:0.20質量%以下を含有し、残部がAlおよび不可避的不純物から構成されるアルミニウム合金板と、アルミニウム合金板の両面を被覆する有機樹脂皮膜とを有する。缶エンド用アルミニウム合金板において、アルミニウム合金板の一方の面及び他方の面をそれぞれ被覆する有機樹脂皮膜の表面を第1面、第2面としたとき、第1面及び第2面の動摩擦係数が0.01以上0.03以下である。圧延方向に対して0°方向、45°方向、90°方向での耐力における最大値と最小値との差が20MPa以下である。ランクフォード値R0と、ランクフォード値R45と、ランクフォード値R90とから算出されるR(AVE)が0.5以上である。
