5154 (A95154) Aluminum

5154 aluminum is a 5000-series aluminum alloy: the main alloying addition is magnesium, and it is formulated for primary forming into wrought products. 5154 is the Aluminum Association (AA) designation for this material. In European standards, it will be given as EN AW-5154. A95154 is the UNS number.

It has been in use since 1932, 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 5154 aluminum include fourteen 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 5154 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 5154 aluminum is notable for containing a comparatively high amount of magnesium (Mg). Magnesium promotes hardenability through both heat treatment and strain hardening mechanisms. It also increases susceptibility to intergranular corrosion.

Aluminum (Al) 94.4 to 96.8
Magnesium (Mg) 3.1 to 3.9
Chromium (Cr) 0.15 to 0.35
Iron (Fe) 0 to 0.4
Silicon (Si) 0 to 0.25
Titanium (Ti) 0 to 0.2
Zinc (Zn) 0 to 0.2
Manganese (Mn) 0 to 0.1
Copper (Cu) 0 to 0.1
Residuals 0 to 0.15
