6008 (AlSiMgV, A96008) Aluminum
6008 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. 6008 is the Aluminum Association (AA) designation for this material. In European standards, it will be given as EN AW-6008. AlSiMgV is the EN chemical designation. And A96008 is the UNS number.
It originally received its standard designation in 1983.
The properties of 6008 aluminum include two common variations. This page shows summary ranges across both of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare 6008 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 6008 aluminum is notable for including vanadium (V). Vanadium is used to reduce grain size and increase recrystallization temperature.
