What Are Uses of 7150 7050 Aluminum Alloys

7150 and 7050 aluminum sheets occupy an important position in the field of high-end manufacturing due to their excellent performance. Although these two aluminum sheets belong to the 7xxx series aluminum alloy (with zinc as the main alloying element), they have their own advantages in composition and performance, and are therefore suitable for different application scenarios.

In terms of chemical composition, the main alloying elements of 7150 aluminum and 7050 aluminum plates are zinc, magnesium, and copper, but the content is different. The zinc content of 7150 aluminum plate is usually 6.2% - 7.0%, the magnesium content is 2.1% - 2.9%, and the copper content is 2.0% - 2.6%. At the same time, a trace amount of zirconium is added to improve the alloy's stress corrosion resistance and recrystallization temperature.

The zinc content of 7050 aluminum sheet is 6.2% - 7.2%, the magnesium content is 2.1% - 2.9%, the copper content is 2.0% - 2.6%, and the addition of zirconium is also key. The subtle difference in composition makes the two have different focuses in performance.

7150 aluminum sheet stands out with its ultra-high strength and good fracture toughness, especially in the T77 heat treatment state, it can maintain high strength while having excellent resistance to stress corrosion cracking.

This feature makes it a "star material" in the aerospace field, and is often used to manufacture key load-bearing structural parts of aircraft, such as wing beams, fuselage frames, etc. For example, in the design and manufacture of large passenger aircraft, 7150 aluminum sheet can effectively reduce the weight of the fuselage, improve fuel efficiency, and ensure the safety and reliability of the structure under complex flight conditions.

7050 aluminum sheet is known for its excellent comprehensive performance. It is not only strong, but also has good fatigue resistance and anti-scaling corrosion performance. In the field of aerospace, it is often used to manufacture landing gear parts, wing skins and other parts that require extremely high strength and durability.

In the field of national defense and military industry, 7050 aluminum sheet also plays an important role. It can be used to manufacture missile launchers, protective armor for armored vehicles, etc. It can withstand frequent impacts and vibrations to ensure the service life and combat performance of equipment.

In addition to aerospace and defense industries, 7150 and 7050 aluminum sheets are also used in high-end sports equipment. Due to its high strength, 7150 aluminum sheets are suitable for manufacturing professional-grade bicycle frames, providing stable and lightweight support for riders; 7050 alloy is often used to make golf club heads due to their good fatigue resistance, improving the accuracy and feel of hitting the ball.
