Abstract
Provided is a composite Al material for a drawn and ironed can from which a drawn and ironed can having brightness can be formed. In a resin coated metal plate used for forming a drawn and ironed can, a first resin layer (20) having a thickness of 0.02 to 2 μm is formed on a surface of an Al plate 10 which forms an outer surface of the can, and a second resin layer 30 having a thickness of 1 to 40 μm is formed on a surface of the Al plate 10 which forms an inner surface of the can. In a penetration test using a TMA device, an insertion amount of a quartz pin when a load of 5 g is applied to the first resin layer at a temperature of 100° C. is 20% or less of a film thickness of the first resin layer. Further, the first resin layer has a room temperature of 10 N/mm2 or more.
