Document Type and Number:
WIPO Patent Application WO/2015/019960
Kind Code:
A1
Abstract:
In the present invention, crystallized substances present in a predetermined surface area of an aluminum foil represent 2% or less of the total surface area. The average surface area per crystallized substance is 2 μm2 or less. The surface roughness (Rz) in the direction perpendicular to the rolling direction is 40 nm or less. The surface roughness (Ra) is 10 nm or less. An aluminum foil for a visible-light-reflecting material is produced by using a roll having a surface roughness (Ra) of 40 nm or less to carry out end-finish cold rolling of the aluminum foil at a rolling reduction of 35% or more.
