5005A (AlMg1(C), 3.3315) Aluminum
5005A aluminum is a 5000-series aluminum alloy: the main alloying addition is magnesium, and it is formulated for primary forming into wrought products. 5005A is the Aluminum Association (AA) designation for this material. In European standards, it will be given as EN AW-5005A. AlMg1(C) is the EN chemical designation. Additionally, the AFNOR (French) designation is A-G0,6.
It originally received its standard designation in 1979.
The properties of 5005A aluminum include 17 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 5005A aluminum to: 5000-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 5005A aluminum is notable for containing comparatively high amounts of magnesium (Mg) and iron (Fe). Magnesium promotes hardenability through both heat treatment and strain hardening mechanisms. It also increases susceptibility to intergranular corrosion. Most of the time, iron is an impurity in aluminum alloys. However, it may be added in quantity to improve strength (particularly at high temperatures) without much impact on electrical properties.
