6005A T5 Aluminium Alloy

About 6xxx Series Alloys

The 6xxx series are versatile, heat treatable, highly formable, weldable and have moderately high strength coupled with excellent corrosion resistance.  Alloys in this series contain silicon and magnesium in order to form magnesium silicide within the alloy.  Extrusion products from the 6xxx series are the first choice for architectural and structural applications.  Alloy 6061 is the most widely used alloy in this series and is often used in truck and marine frames.  Additionally, the iPhone 6 extrusion was made from 6xxx series alloy.


6005A T5 is a medium structural alloy. Good extrusion characteristics with good surface finish. Available in structural shapes of all types, rod, bar, and tube, offered in the T5 temper.


Medium structural applications where surface finish is important. Marine, Transport applications.
