5049 (AlMg2Mn0.8, 3.3527, A95049) Aluminum

5049 aluminum is a 5000-series aluminum alloy: the main alloying addition is magnesium, and it is formulated for primary forming into wrought products. 5049 is the Aluminum Association (AA) designation for this material. In European standards, it will be given as EN AW-5049. A95049 is the UNS number. Additionally, the EN chemical designation is AlMg2Mn0,8. And the AFNOR (French) designation is A-G2,5MC.

It originally received its standard designation in 1979.

The properties of 5049 aluminum include 19 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 5049 aluminum to: 5000-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.
