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.

Applications of 7075 Aluminum
Type 7075 aluminum is one the strongest aluminum alloys. Its high yield strength (>500 MPa) and its low density make the material a fit for applications such as aircraft parts or parts subject to heavy wear. While it is less corrosion resistant than other alloys (such as 5052 aluminum alloy, which is exceptionally resistant to corrosion), its strength more than justifies the downsides. Some major applications of 7075 aluminum alloy include:
Aircraft fittings
Gears and shafts
Missile parts
Regulating valve parts
Worm gears
Aerospace/defense applications
