Document Type and Number:
WIPO Patent Application WO/2001/004369
Kind Code:
A1
Abstract:
An aluminum alloy comprising 0.0001 mass % to 0.03 mass % of copper, 0.0005 mass % to 0.2 mass % of silicon, 0.5 mass % to 4 mass % of Mn, 0.5 mass % to 3 mass % of Fe, the balance being aluminum and inevitable impurities; and an aluminum alloy further comprising at least one member of 0.01 mass % to 0.5 mass % of Cr, 0.01 mass % to 0.5 mass % of Ti and 0.01 mass % to 0.5 mass % of Zr. A method for manufacturing an aluminum alloy foil which comprises heating an aluminum alloy to a temperature from 350°C to 580°C, subjecting the alloy in an ingot form to a hot rolling of a starting temperature of 350°C to 530°C immediately after the above heating or after keeping the alloy ingot at a temperature from 350°C to 580°C for a time up to 15 hr, and then subjecting the resultant sheet to a cold rolling, followed by subjecting to a softening treatment.
