Aluminium, Commercial Alloy
4015 H14 Sheet
High quality general purpose aluminium alloy.
Aluminium alloy 4015 is a high quality general purpose alloy. It is a close relation to 3103 AlMn alloy, but with a 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.
Please note that the mechanical properties quoted are for H14 temper.
