ALUMINUM ALLOY 7075 GENERAL DESCRIPTION:
What is Aluminum 7075?
Aluminum 7075 is a heat-treatable aluminum alloy with zinc as the primary alloying element. It has moderated formability when in the fully soft, annealed temper and can be heat-treated to strength levels that are comparable to many steel alloys.
CHEMICAL COMPOSITION LIMITS:
Compositions are listed as weight percent. Limits are given as a maximum unless indicated as a range.
