What is 7075-T6 aluminium?
With zinc as the dominant alloying element, the 7075 aluminum alloy (also known as aircraft aluminum or aerospace aluminum) was the first alloy of high strength composed by Al-Zn-Mg-Cu that was able to successfully combine the perks of the inclusion of chromium to develop high-stress-corrosion cracking resistance in sheet products. The composition of the 7075 aluminum alloy consists of 87.1 – 91.4% aluminum, while zinc is present in a concentration of 5 – 6%. It also contains 2.1 – 2.9% magnesium, 1.2 – 2%, and no more than 0.5% of silicon, titanium, chromium, iron, manganese, and other constituting metals.

The 7075-T6 aluminum is a 7075 aluminum alloy with a T6 temper, which is achieved by treating it with solution heat, homogenizing the 7075 casts at 450 °C for several hours, quenching, and then artificially aging it at 120 °C for 24 hours, which is around the time when it meets standard property requirements. This process guarantees achieving the peak strength of this alloy.

Application and Uses
The set of properties that 7075-T6 aluminum offers make it a solid choice for universal use in a variety of industries while remaining a favorite for the industries of aerospace, marine, and transportation due to its excellent strength-to-weight ratio. Other very common uses include top-line bicycle components, tool-making, gliders, meter gears, fuse parts, missile parts, worm gears, keys, regulating valve parts, and many other different commercial aircraft, aircraft fittings, and aerospace and defense equipment and components.

Conclusion
The 7075-T6 aluminum is the preferred choice for the aerospace, marine, and transportation industries, where low weight and high-stress resistance are crucial factors. However, its use is very popular in a variety of other industries, due to its well-balanced set of properties.
