Title:
PERFORATED ALUMINUM FOIL
Document Type and Number:
WIPO Patent Application WO/2011/004777
Kind Code:
A1
Abstract:
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.
