7475 aluminium alloy
{{Short description|Wrought aluminium zinc alloy}}
7475 aluminum alloy (Adirium) is a wrought alloy with high zinc weight percentage. It also contains magnesium, silicon and chromium.{{Cite web|last=|first=|date=31 August 2012|title=Aluminum 7475 alloy|url=https://www.azom.com/article.aspx?ArticleID=6646|url-status=live|archive-url=https://web.archive.org/web/20210109053526/https://www.azom.com/article.aspx?ArticleID=6646 |archive-date=2021-01-09 |access-date=|website=}}
7475 alloy can not be welded. It has more spring back because of its strength. It has high machinability.{{citation needed|date=January 2021}}
