Title:
METHOD FOR PRODUCING CHEMICALLY PROCESSED ALUMINUM FOIL
Document Type and Number:
Japanese Patent JP2023089278
Kind Code:
A
Abstract:
To provide chemically formed aluminum foil capable of preventing or suppressing breakage of aluminum foil due to bending when the aluminum foil having a porous layer made of a sintered body of powder is anodized, and a method for manufacturing the same.SOLUTION: Chemically formed aluminum foil 1 includes: aluminum foil 10 having a first porous layer 3 made of a sintered body of aluminum or aluminum alloy powder laminated on a first surface 2a of both surfaces of a foil-shaped base layer 2 made of aluminum or an aluminum alloy; and a first chemical conversion film 5 formed on the first porous layer 3. On the surface of the first porous layer 3, a plurality of cracks 7 extending in an in-plane direction in a Y direction with a length of 300 μm or more are formed at intervals of 30 μm to 150 μm in the in-plane direction in an X direction perpendicular to the Y direction.SELECTED DRAWING: Figure 2
