7075 T6/T7 Aluminum Sheet/Plate alloy for aerospace application

7075 T6/T7  Aluminum Sheet/Plate alloy for aerospace application

Alloy 7075 aluminum sheets and plates are the outstanding member of the 7xxx series and remains the baseline among the highest strength alloys available. Zinc is the primary alloying element giving it strength comparable to steel. Temper T651 possesses good fatigue strength, fair machinability, resistance welding and corrosion resistance ratings. 

The main alloying element in 7075 aluminum sheets and plates is zinc. 7075 was the first Al-Zn-Mg-Cu high-strength alloy that utilized the addition of chromium as an alloying element, resulting in good stress-corrosion cracking resistance for sheet products. Although 7075 Aluminum has no weldability, a low level of corrosion resistance and only offers average performance this alloy offers considerable fatigue strength. With a high strength-to-density ratio, 7075 aluminum sheets and plates are often used in applications such as rock climbing equipment, hang glider airframes, and military rifles. Not surprisingly, 7075 aluminum is still considered the go-to alloy for the aircraft and aerospace industries today.
