Aluminum Alloy 3003
98.2 Al | 0.20 Cu | 1.20 Mn | 0.7 Fe | 0.10 Zn | 0.6 Si | "S" Weight Factor - 3.73
Summary: 3000 series – Manganese is the major alloying element of alloys in this group, which are generally non-heat-treatable. Because only a limited percentage of manganese, up to about 1.5 percent, can be effectively added to aluminum, it is used as a major element in only a few instances. One of these, however, is the popular 3003, which is widely used as a general-purpose alloy for moderate-strength applications requiring good workability.
