Aeronautical Aluminum Alloys
There are at least a dozen wrought aeronautical aluminum alloys, mainly concentrated in two types of alloys, Al-Cu and Al-Zn. Al-Cu is a medium to high strength, high fatigue, high corrosion resistance aluminum alloy, the so-called 2xxx series aluminum alloy, including 2024, 2324, 2524 aluminum etc. Al-Zn belongs to high-strength, high-fatigue aluminum alloys, the so-called 7xxx series aluminum alloy,…
