7075 Aluminum Alloy and Its Application
- Sep 07, 2017 -

Aluminum alloy 7075 is an aluminum alloy, with zinc as the primary alloying element,a small amount of magnesium and copper are added in it. It is strong, with a strength comparable to many steels, and has good fatigue strength and average machinability. But the copper content makes it very difficult to weld. It has lower resistance to corrosion than many other Al alloys, but has significantly better corrosion resistance than the 2000 alloys.And its anodizes id very beautiful. Its relatively high cost limits its use to applications where cheaper alloys are not suitable. 7075 aluminum alloy is one of the most powerful commercial alloys.


7000 series aluminum alloys are often used in transport applications, including marine, automotive and aviation, due to its high strength-to-density ratio. Aluminum alloy 7075 are used extensively for stringers, wings, fuselage skins and other structural requirements of aircrafts.
