Introduced by Alcoa in 1943, alloy 7075 has been the standard workhorse 7XXX series alloy within the aerospace industry ever since.
It was the first successful Al-Zn-Mg-Cu high strength alloy using the beneficial effects of the alloying addition of chromium to develop
good stress-corrosion cracking resistance in sheet products. Although other 7XXX alloys have since been developed with improved
specificproperties, alloy 7075 remains the baseline with a good balance of properties required for aerospace applications.
Alloy 7075 is available in bare ~and alclad sheet ~and plate product forms in the annealed state as well as several tempers
of the T6, T73 ~and T76 types.
