Title
(EN) PERFORATED ALUMINUM FOIL
(FR) FEUILLE D'ALUMINIUM PERFORÉE
(JA) アルミニウム貫通箔
Abstract
(EN)
Disclosed is a perforated aluminum foil which has high strength and a plurality of through holes, since the perforated aluminum foil has a high cube orientation occupancy in spite of a thin foil thickness. Specifically disclosed is a perforated aluminum foil which is composed of 5-80 ppm by weight of Fe, 5-100 ppm by weight of Si and 10-100 ppm by weight of Cu, with the balance made up of Al and unavoidable impurities. The perforated aluminum foil is characterized in that: (1) the foil thickness is not more than 50 μm; (2) the foil has a plurality of through holes penetrating therethrough from the front surface to the back surface; and (3) the ratio of the vertical through hole occupancy (c) (%) to the foil thickness (t) (μm) in the perforated aluminum foil, namely c/t is not less than 1.4.
(FR)
L'invention porte sur une feuille d'aluminium perforée qui a une résistance élevée et une pluralité de trous traversants, étant donné que la feuille d'aluminium perforée a une occupation d'orientation cubique élevée en dépit d'une faible épaisseur de feuille. De façon spécifique, l'invention porte sur une feuille d'aluminium perforée qui est composée de 5-80 ppm en poids de Fe, 5-100 ppm en poids de Si et 10-100 ppm en poids de Cu, le complément étant constitué par Al et les impuretés inévitables. La feuille d'aluminium perforée est caractérisée par le fait que : (1) l'épaisseur de feuille n'est pas supérieure à 50 µm ; (2) la feuille a une pluralité de trous traversants pénétrant à travers celle-ci de la face avant à la face arrière ; (3) le rapport d'occupation des trous traversants verticaux (c) (%) à l'épaisseur de la feuille (t) (µm) dans la feuille d'aluminium perforée, à savoir c/t, n'est pas inférieur à 1,4.
(JA)
 本発明は、箔厚みが薄いにもかかわらず、高い立方体方位占有率を有するがゆえに、高強度で多くの貫通孔を有するアルミニウム貫通箔を提供するものである。 本発明のアルミニウム貫通箔は、Fe:5~80重量ppm、Si:5~100重量ppm、Cu:10~100重量ppmならびに残部:Al及び不可避不純物からなるアルミニウム貫通箔であって、(1)箔厚みが50μm以下であり、(2)箔表面から裏面に至る貫通孔を複数有し、(3)当該アルミニウム貫通箔における垂直貫通孔占有率c(%)と前記箔厚みt(μm)の比率[c/t]が1.4以上であることを特徴とする。
