7075 aluminium alloy (AA7075) is an aluminium alloy with zinc as
the primary alloying element. It has excellent mechanical
properties and exhibits good ductility, high strength, toughness,
and good resistance to fatigue. It is more susceptible to
embrittlement than many other aluminium alloys because of
microsegregation, but has significantly better corrosion resistance
than the alloys from the 2000 series. It is one of the most
commonly used aluminium alloys for highly stressed structural
applications and has been extensively used in aircraft structural
parts.
7075 aluminium alloy's composition roughly includes 5.6–6.1% zinc,
2.1–2.5% magnesium, 1.2–1.6% copper, and less than a half percent
of silicon, iron, manganese, titanium, chromium, and other metals.
It is produced in many tempers, some of which are 7075-0, 7075-T6,
7075-T651.
The first 7075 was developed in secret by a Japanese company,
Sumitomo Metal, in 1935, but reverse engineered by Alcoa in 1943,
after examining a captured Japanese aircraft. 7075 was standardized
for aerospace use in 1945. 7075 was eventually used for airframe
production in the Imperial Japanese Navy.
