5110A Aluminum

5110A aluminum is a 5000-series aluminum alloy: the main alloying addition is magnesium, and it is formulated for primary forming into wrought products. 5110A is the Aluminum Association (AA) designation for this material. In European standards, it will be given as EN AW-5110A.

It received its standard designation in 2005, making it a fairly young material.

It has the highest electrical conductivity and the highest thermal conductivity among 5000-series alloys.

The properties of 5110A aluminum include eight 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 5110A 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 5110A 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) 98.5 to 99.8
Magnesium (Mg) 0.2 to 0.6
Iron (Fe) 0 to 0.25
Manganese (Mn) 0 to 0.2
Copper (Cu) 0 to 0.2
Silicon (Si) 0 to 0.15
Zinc (Zn) 0 to 0.030
Residuals 0 to 0.1
