摘要： The invention relates to an end wall of a metal container having a score therein. The end wall is made of a composite metal sheet made of two or more metal layers, one of the layers being made of an aluminum alloy of high strength (e.g. a high magnesium alloy such as AA5182, AA5042 or AA5082, optionally with increased Mg), and another of the layers being made of an aluminum alloy having a good resistance to stress corrosion cracking (e.g. aluminum alloys AA3004, AA3104, AA5006 or AA5005), wherein at least the bottom of the score is formed by a surface of the alloy of good resistance to stress corrosion cracking.
