6013 (AlMg1Si0.8CuMn, A96013) Aluminum
6013 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. 6013 is the Aluminum Association (AA) designation for this material. In European standards, it will be given as EN AW-6013. A96013 is the UNS number. Additionally, the EN chemical designation is AlMg1Si0,8CuMn.
It originally received its standard designation in 1983.
The properties of 6013 aluminum include three 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 6013 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 6013 aluminum is notable for containing comparatively high amounts of magnesium (Mg) and copper (Cu). Magnesium promotes hardenability through both heat treatment and strain hardening mechanisms. It also increases susceptibility to intergranular corrosion. Copper is used to improve strength. This comes at the cost of a decrease in corrosion resistance and weldability.
