6110A (AlMg0.9Si0.9MnCu) Aluminum
6110A aluminum is a 6000-series aluminum alloy: there is significant alloying with both magnesium and silicon, and the alloy is formulated for primary forming into wrought products. 6110A is the Aluminum Association (AA) designation for this material. In European standards, it will be given as EN AW-6110A. Additionally, the EN chemical designation is AlMg0,9Si0,9MnCu.
It received its standard designation in 1996, making it a fairly young material.
The properties of 6110A aluminum include three 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 6110A aluminum to: 6000-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 6110A aluminum is notable for including zirconium (Zr). Zirconium is used to increase an alloy's recrystallization temperature, which increases the temperature at which the alloy can be used without permanent loss of mechanical properties.
