RESIN-COATED 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 aluminium alloy sheet for a can body containing Mg of 0.1 to 6.0%, Fe of 0.01 to 0.5%, Mn of 0.01 to 0.85% and Fe+Mn of less than 1.3% and made to a drawn ironed can after being coated with a resin in advance, where surface roughness Rq in a rolling mark direction on a surface which is an outermost side of the drawn ironed can of the sheet is 0.12 μm or less, area percentage of an Fe based crystal having maximum length of 0.3 μm or more in a surface layer part up to 15 μm depth in a sheet thickness direction from the surface which is the outermost side of the drawn ironed can of the sheet is less than 2.4% and especially glossiness of 0° position part or the like of the can of the Figure 1 is excellent.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
