4015 (AlSi2Mn) Aluminum
4015 aluminum is a 4000-series aluminum alloy. The main alloying addition is silicon. 4015 is the Aluminum Association (AA) designation for this material. In European standards, it will be given as EN AW-4015. AlSi2Mn is the EN chemical designation. Additionally, the UNS number is A94015.
It originally received its standard designation in 1989.
The properties of 4015 aluminum include six 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 4015 aluminum to: 4000-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.
Many users now prefer to use alloy 4015 having switched from other alloys such as 1050 and 3103. The corrosion resistance of alloy 4015 is similar to the 3000 series alloys. Suitable for most applications in mill finish or painted, it is not recommended for use in aggressive environments. The main alloying addition is silicon. 4015 is the Aluminum Association (AA) designation for this material. In European standards, it will be given as EN AW-4015. AlSi2Mn is the EN chemical designation. Additionally, the UNS number is A94015.
