2030 (AlCu4PbMg, A92030) Aluminum

2030 aluminum is a 2000-series aluminum alloy: the main alloying addition is copper, and it is formulated for primary forming into wrought products. 2030 is the Aluminum Association (AA) designation for this material. In European standards, it will be given as EN AW-2030. AlCu4PbMg is the EN chemical designation. A92030 is the UNS number. Additionally, the AFNOR (French) designation is A-U4Pb.

It originally received its standard designation in 1972.

The properties of 2030 aluminum include seven common variations. This page shows summary ranges across all of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare 2030 aluminum to: 2000-series alloys (top), all aluminum alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.

Alloy Composition

Among wrought aluminum alloys, the composition of 2030 aluminum is notable for including lead (Pb) and bismuth (Bi). Lead is used to improve machinability at the cost of toxicity and a decrease in weldability. Bismuth is used to improve machinability at the cost of a decrease in weldability.

Aluminum (Al)Al 88.9 to 95.2
Copper (Cu)Cu 3.3 to 4.5
Lead (Pb)Pb 0.8 to 1.5
Magnesium (Mg)Mg 0.5 to 1.3
Manganese (Mn)Mn 0.2 to 1.0
Silicon (Si)Si 0 to 0.8
Iron (Fe)Fe 0 to 0.7
