Title:
ALUMINUM ALLOY FOIL AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2017/135108
Kind Code:
A1
Abstract:
Provided is an aluminum alloy foil having high strength and elongation even after heat treatment in an electrode production step or the like. The aluminum alloy foil contains Fe: 1.0-2.0% and Mn: 0.05% or less by mass% as chemical components, with the balance consisting of Al and unavoidable impurities. The aluminum alloy foil has an average grain size on the foil surface of 2.5 μm or less, and the crystal orientation area proportion ratio A｛112｝<111>/ A｛101｝<121> is 3.0 or higher. Where, A｛112｝<111> is the proportion of the area of crystal grains having a crystal orientation within 15° from {112}<111> to the total area in an orientation mapping image of the foil surface by electron backscatter diffraction, and A｛101｝<121> is the proportion of the area of crystal grains having a crystal orientation within 15° from {101}<121> to the total area in the orientation mapping image.
