4015 Aluminum Alloy Plate


4015 aluminium alloy 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. 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.
