2007-T3511 Aluminum
2007-T3511 aluminum is 2007 aluminum in the T3511 temper. To achieve this temper, the metal is solution heat-treated, stress relieved, then naturally aged. The stress relief is accomplished by stretching the metal by an amount that depends on the type of standard wrought product being made (extrusion or tube). The metal is straightened after the stretching operation. This temper is closely related to T3510, which does not permit such straightening.
The graph bars on the material properties cards below compare 2007-T3511 aluminum to: 2000-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.
