3005 (AlMn1Mg0.5, 3.0525, A93005) Aluminum

3005 aluminum is a 3000-series aluminum alloy: the main alloying addition is manganese, and it is formulated for primary forming into wrought products. 3005 is the Aluminum Association (AA) designation for this material. In European standards, it will be given as EN AW-3005. A93005 is the UNS number. Additionally, the EN chemical designation is AlMn1Mg0,5. And the AFNOR (French) designation is A-MG0,5.

It originally received its standard designation in 1954.

The properties of 3005 aluminum include thirteen 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 3005 aluminum to: 3000-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 3005 aluminum is notable for containing a comparatively high amount of manganese (Mn). Manganese is used to improve strength without a proportional reduction in ductility. It also improves workability by controlling the grain structure of the alloy.

Aluminum (Al) 95.7 to 98.8
Manganese (Mn) 1.0 to 1.5
Magnesium (Mg) 0.2 to 0.6
Iron (Fe) 0 to 0.7
Silicon (Si) 0 to 0.6
Copper (Cu) 0 to 0.3
Zinc (Zn) 0 to 0.25
Chromium (Cr) 0 to 0.1
Titanium (Ti) 0 to 0.1
Residuals 0 to 0.15
