ALUMINUM ALLOY SHEET FOR DRAWN IRONED CAN EXCELLENT IN GLOSSINESS AFTER MAKING CAN AND RESIN COATED ALUMINUM ALLOY SHEET FOR DRAWN IRONED CAN

摘要

PROBLEM TO BE SOLVED: To provide an aluminum alloy sheet for a can body capable of enhancing glossiness of a drawn ironed can surface.SOLUTION: There is provided an aluminum alloy sheet for a can body having a specific composition, which is made to a drawn ironed can after being coated with a resin in advance, where average percentage of small tilt angle grain boundary with tilt of 5 to 15° which affects largely on glossiness of a drawn ironed can surface, out of a crystal grain structure on the surface part of the sheet, is controlled to make a crystal grain structure mainly containing large tilt grain boundary, and particularly, glossiness of a 0° position part of the can is excellent.SELECTED DRAWING: None
