航空鋁7075熱處理及物理性能

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.

Alloy 7075 sheet and plate products have application throughout aircraft and aerospace structures where a combination of high strength with moderate toughness

and corrosion resistance are required.

Typical applications are alclad skin sheet, structural plate components up to 4 inches in thickness and general aluminum

aerospace applications.
