Aluminium alloy 4925 is the Pechiney equivalent of Alloy 4015 - A high quality general purpose alloy featuring good ductility coupled with mechanical strength. A close relation to 3103 Al Mn alloy, but with higher Silicon content, this alloy can be welded, anodized* or painted. It should be noted that the anodized finish of alloy 4925 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 4925 having switched from other alloys such as 1050 and 3103.
The corrosion resistance of alloy 4925 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.
Please note that the mechanical properties quoted are for H12 temper - Mechanical Properties for other tempers are shown on page 2.
Aluminim alloy 4925 has similarities to Alloy 4015 but may not be a direct equivalent
The most common tempers for 4925 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
- O - Soft
Alloy 4015 is only available as sheet
