AA 2017 T4 Alloy – Heat‑Treatable Aluminum Grade with Superior Strength and Machinability
Aluminum AA 2017 is a heat treatable wrought alloy that offers decent strength, ductility, and good machinability. Aluminum AA 2017 offers more strength than Aluminum 2011, and has fair workability and corrosion resistance. As with many aluminum alloys, Aluminum AA 2017 should not be welded as it reduces the alloy’s corrosion resistance.
