Claim 19:
20. A method for generating an aluminum-copper alloy using aluminum alloy scrap, said method comprising:
detecting a chemical composition of the aluminum alloy scrap and adding a suitable amount of copper or copper alloy according to a composition requirement of a target aluminum-copper alloy;
vacuum smelting the aluminum alloy scrap and the copper or copper alloy in a vacuum furnace, wherein at least one of zinc and magnesium is removed and an aluminum-copper alloy solution is formed;
filtering the aluminum-copper alloy solution using a filter to obtain an aluminum-copper alloy melt comprising the target aluminum-copper alloy; and
casting the target aluminum-copper alloy from said melt,
wherein the copper or copper alloy is added with the aluminum alloy scrap before the step of vacuum smelting the aluminum alloy scrap and the copper or copper alloy.
