6016 (AlSi1.2Mg0.4, A96016) Aluminum

6016 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. 6016 is the Aluminum Association (AA) designation for this material. In European standards, it will be given as EN AW-6016. A96016 is the UNS number. Additionally, the EN chemical designation is AlSi1,2Mg0,4.

It originally received its standard designation in 1984.

It can have the highest ductility among the 6000-series alloys in the database.

The properties of 6016 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 6016 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 6016 aluminum is notable for containing a comparatively high amount of silicon (Si). Silicon is used to increase strength at the expense of ductility. It also lowers the melting temperature and raises the fluidity of the alloy.

Aluminum (Al) 96.4 to 98.8
Silicon (Si) 1.0 to 1.5
Magnesium (Mg) 0.25 to 0.6
Iron (Fe) 0 to 0.5
Manganese (Mn) 0 to 0.2
Zinc (Zn) 0 to 0.2
Copper (Cu) 0 to 0.2
Titanium (Ti) 0 to 0.15
Chromium (Cr) 0 to 0.1
Residuals 0 to 0.15
