Aluminum alloy coating process and method

A process, comprising:

• (a) receiving a cast aluminum alloy sheet, the aluminum alloy sheet comprising:
• no more than about 6 wt. % magnesium;
• no more than about 1.8 wt. % by weight manganese;
• no more than about 0.50 wt. % copper;
• no more than about 1.8 wt. % silicon;
• no more than about 0.40 wt. % chromium;
• no more than about 2.8 wt. % zinc;
• no more than about 0.10 wt. % nickel;
• no more than about 1 wt. % iron;
• no more than about 0.20 wt. % titanium;
• and
• no more than about 0.15 wt. % other impurities;
• (b) applying a coating composition to the aluminum alloy sheet;
• and
• (c) curing the coating composition by at least one of ultraviolet light and an electron beam to form a coated aluminum alloy sheet.
