1060 (Al99.6, A91060) Aluminum
1060 aluminum is a 1000-series aluminum alloy: it is considered commercially pure, and is formulated for primary forming into wrought products. 1060 is the Aluminum Association (AA) designation for this material. In European standards, it will be given as EN AW-1060. A91060 is the UNS number. Additionally, the EN chemical designation is Al99,6.
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 tensile strength among the 1000-series alloys in the database.
The properties of 1060 aluminum include eleven 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 1060 aluminum to: 1000-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 1060 aluminum is notable for including vanadium (V). Vanadium is used to reduce grain size and increase recrystallization temperature.
