Material: 7075-t6 Aluminum

Aluminium alloy 7075 is an aluminium alloy, with zinc as the primary alloying element. It is strong, with a strength comparable to many steels, and has good fatigue strength and average machinability, but has less resistance to corrosion than many other Al alloys. Its relatively high cost limits its use to applications where cheaper alloys are not suitable. The T6 temper is usually achieved by homogenizing the cast 7075 at 450C for several hours, and then aging at 120C for 24 hours. This yields the peak strength of the 7075 alloy.
