6162 (A96162) Aluminum

6162 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. 6162 is the Aluminum Association (AA) designation for this material. In European standards, it will be given as EN AW-6162. A96162 is the UNS number.

It originally received its standard designation in 1959.

The properties of 6162 aluminum include six 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 6162 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 6162 aluminum is notable for containing comparatively high amounts of magnesium (Mg) and silicon (Si). Magnesium promotes hardenability through both heat treatment and strain hardening mechanisms. It also increases susceptibility to intergranular corrosion. 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) 96.7 to 98.9
Magnesium (Mg) 0.7 to 1.1
Silicon (Si) 0.4 to 0.8
Iron (Fe) 0 to 0.5
Zinc (Zn) 0 to 0.25
Copper (Cu) 0 to 0.2
Manganese (Mn) 0 to 0.1
Chromium (Cr) 0 to 0.1
Titanium (Ti) 0 to 0.1
Residuals 0 to 0.15
