5026 (AlMg4.5MnSiFe, A95026) Aluminum
5026 aluminum is a 5000-series aluminum alloy: the main alloying addition is magnesium, and it is formulated for primary forming into wrought products. 5026 is the Aluminum Association (AA) designation for this material. In European standards, it will be given as EN AW-5026. A95026 is the UNS number. Additionally, the EN chemical designation is AlMg4,5MnSiFe.
It received its standard designation in 2001, making it a fairly young material.
The properties of 5026 aluminum include five 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 5026 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 5026 aluminum is notable for containing comparatively high amounts of manganese (Mn) and magnesium (Mg). Manganese is used to improve strength without a proportional reduction in ductility. It also improves workability by controlling the grain structure of the alloy. Magnesium promotes hardenability through both heat treatment and strain hardening mechanisms. It also increases susceptibility to intergranular corrosion.
