Aluminium alloy 4015 is a high quality general purpose alloy featuring good ductility coupled with mechanical strength. A close relation to 3103 AlMn alloy, but with higher Silicon content, this alloy can be welded, anodized* or painted. It should be noted that the anodized finish of alloy 4015 will be much darker and less reflective that on alloys 1050 or 3103 so this is not recommended for decorative applications. 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.

Temper Types
The most common tempers for 4015 aluminium are:
- H14 - Work hardened by rolling to half hard, not annealed after rolling
- H16 - Work hardened by rolling to three-quarter hard, not annealed after rolling
- H12 - Work hardened by rolling to quarter hard, not annealed after rolling
- H18 - Work hardened by rolling to fully hard, not annealed after rolling
Weldability
Suitable for MIG and TIG welding using normal aluminium welding conditions Recommended welding wire is 4043 (Al Si5)
