2219 aluminum is a 2000-series aluminum alloy: the main alloying addition is copper, and it is formulated for primary forming into wrought products. 2219 is the Aluminum Association (AA) designation for this material. In European standards, it will be given as EN AW-2219. AlCu6Mn is the EN chemical designation. A92219 is the UNS number. Additionally, the AFNOR (French) designation is A-U6MT.
It originally received its standard designation in 1954. This material is well established: the Further Reading section below cites a number of published standards, and that list is not necessarily exhaustive.
It can have the lowest electrical conductivity among 2000-series alloys. In addition, it can have the lowest tensile strength and the lowest thermal conductivity.
The properties of 2219 aluminum include thirteen 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 2219 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.
