[2] 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.
As is the case for all 7075 aluminum alloys, 7075-0 is highly corrosion-resistant combined with generally acceptable strength profile.
[11] T7 temper is achieved by overaging (meaning aging past the peak hardness) the material.
In contrast to the T6 temper, these eta particles are much larger and prefer growth along the grain boundaries.
The aircraft was known for its excellent maneuverability which was facilitated by the higher strength of 7075 compared to previous aluminum alloys.
7000 series alloys such as 7075 are often used in transport applications due to their high specific strength, including marine, automotive and aviation.
[7][14] These same properties lead to its use in rock climbing equipment, bicycle components, inline-skating-frames and hang glider airframes are commonly made from 7075 aluminium alloy.
In particular high-quality M16 rifle lower and upper receivers, as well as extension tubes, are typically made from 7075-T6 alloy.
Desert Tactical Arms, SIG Sauer, and French armament company PGM use it for their precision rifles.
It is also commonly used in shafts for lacrosse sticks, such as the STX sabre, and camping knife and fork sets.
Aluminum rods do not have the fatigue life of forged steel rods, but have less mass than their steel counterparts, resulting in lower mechanical stress during periods in which an engine is operated under full-throttle, high-RPM conditions.
