The higher the value, the smaller the content of the aluminum alloy, and the trace elements common in each series are easily different, which can change the properties of these series of aluminum alloys. Their specific meanings are as follows. The first digit indicates the main addition of alloying elements. "1" indicates pure aluminum, "2" indicates that the main alloying element is copper, "3" means that the main alloying element is manganese or manganese and magnesium, "4" means that the main alloying element is silicon, "5" means that the main alloying element is magnesium, "6" means that the main alloying element is silicon and magnesium, "7" indicates that the main alloying element is zinc and magnesium, and "8" indicates a new alloy that does not belong to the above alloy series.
