5005 (AlMg1(B), N41, A95005) Aluminum

5005 aluminum is a 5000-series aluminum alloy: the main alloying addition is magnesium, and it is formulated for primary forming into wrought products. 5005 is the Aluminum Association (AA) designation for this material. In European standards, it will be given as EN AW-5005. AlMg1(B) is the EN chemical designation. N41 is the British Standard (BS) designation. And A95005 is the UNS number.

It has been in use since 1935, but has only received its standard designation in 1954. This material is well established: the Further Reading section below cites a number of published standards, and that list is not necessarily exhaustive.

The properties of 5005 aluminum include 16 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 5005 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 5005 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.

Aluminum (Al) 97 to 99.5
Magnesium (Mg) 0.5 to 1.1
Iron (Fe) 0 to 0.7
Silicon (Si) 0 to 0.3
Zinc (Zn) 0 to 0.25
Manganese (Mn) 0 to 0.2
Copper (Cu) 0 to 0.2
Chromium (Cr) 0 to 0.1
Residuals 0 to 0.15
