# 6110 (6110-T9, A96110) Aluminum

6110 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. Cited properties are appropriate for the T9 temper. To achieve this temper, the metal is solution heat-treated, artificially aged, then strain hardened. 6110 is the Aluminum Association (AA) designation for this material. In European standards, it will be given as EN AW-6110. A96110 is the UNS number.

It originally received its standard designation in 1979.

It has the highest tensile strength among the 6000-series alloys in the database.

The graph bars on the material properties cards below compare 6110 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 6110 aluminum is notable for containing a comparatively high amount of silicon (Si). Silicon is used to increase strength at the expense of ductility. It also lowers the melting temperature and raises the fluidity of the alloy.
