6082 (AlSi1MgMn, 3.2315, H30, A96082) Aluminum
6082 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. 6082 is the Aluminum Association (AA) designation for this material. In European standards, it will be given as EN AW-6082. AlSi1MgMn is the EN chemical designation. H30 is the British Standard (BS) designation. A96082 is the UNS number. Additionally, the AFNOR (French) designation is A-SGM0,7. Older literature may refer to this material as CSA SG11R, but this is now discouraged.
It originally received its standard designation in 1972. This material is well established: the Further Reading section below cites a number of published standards, and that list is not necessarily exhaustive.
The properties of 6082 aluminum include twelve 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 6082 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 6082 aluminum is notable for containing comparatively high amounts of silicon (Si) and magnesium (Mg). Silicon is used to increase strength at the expense of ductility. It also lowers the melting temperature and raises the fluidity of the alloy. Magnesium promotes hardenability through both heat treatment and strain hardening mechanisms. It also increases susceptibility to intergranular corrosion.
