6360 (AlSiMgMn, A96360) Aluminum
6360 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. 6360 is the Aluminum Association (AA) designation for this material. In European standards, it will be given as EN AW-6360. AlSiMgMn is the EN chemical designation. And A96360 is the UNS number.
It received its standard designation in 2001, making it a fairly young material.
The properties of 6360 aluminum include four 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 6360 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 6360 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.
