5657 (Al99.85Mg1(A), A95657) Aluminum

5657 aluminum is a 5000-series aluminum alloy: the main alloying addition is magnesium, and it is formulated for primary forming into wrought products. 5657 is the Aluminum Association (AA) designation for this material. In European standards, it will be given as EN AW-5657. A95657 is the UNS number. Additionally, the EN chemical designation is Al99,85Mg1(A).

It originally received its standard designation in 1960.

The properties of 5657 aluminum include five 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 5657 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.

Alloy Composition

Among wrought aluminum alloys, the composition of 5657 aluminum is notable for including gallium (Ga) and vanadium (V). Gallium is used to improve corrosion resistance and to modify an alloy's response to etching, brightening, and similar treatments. Vanadium is used to reduce grain size and increase recrystallization temperature.
