8011A (AlFeSi(A)) Aluminum

8011A aluminum is an otherwise-unclassified alloy of aluminum. 8011A is the Aluminum Association (AA) designation for this material. In European standards, it will be given as EN AW-8011A. AlFeSi(A) is the EN chemical designation.

It originally received its standard designation in 1979.

It can have the highest ductility among the otherwise unclassified aluminums in the database.

The properties of 8011A aluminum include eight 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 8011A aluminum to: otherwise unclassified aluminums (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.
