Due to 7075 aluminum sheet excellent ratio for weight-to-strength, it can be used in applications involving structural parts that are highly stressed.
It’s a popular choice for use in applications in commercial aircraft components and aerospace and defense equipment. 7075 aluminum sheet always called aircraft grade aluminum sheet.
The weldability of this metal is low, but the formability is great. When forging is used, it’s required that the alloy be placed in temperatures between 700 and 900 degrees F. Afterwards, solution heat treatment should be used.
General welding with 7075 aluminum alloy is not recommended. However, you may get good results when resistance welding alloys. The application of arc or gas welding may reduce the natural corrosion resistance of the alloy.
Due to the excellent performance of 7075 alloy, high strength-to-weight ratio, excellent machinability, corrosion resistance, etc., 7075 aluminum sheet is often used in the aerospace field.
7075 aluminum is mainly used for the windward parts of the whole machine, such as the upper outer panel of the wing, the longitudinal beam, the wing rib, the empennage, the fixing of the fuselage bulkhead, etc.
7075 aluminum sheet also has important applications in automobile manufacturing. It can be used to manufacture high-performance racing components such as body frames, chassis structures and high-performance engine parts, helping to improve the car’s performance and fuel efficiency.

The high strength-to-weight ratio makes 7075 aluminum alloy play an important role in the lightweight of automobiles.
7075 aluminum sheet is used in the battery pack casing of Tesla electric vehicles to provide better impact and corrosion resistance
7075 aluminum plate can also be used to manufacture marine engineering structures, such as ships, offshore platforms, etc.
Due to its corrosion resistance and high strength, it can ensure the safety and durability of marine engineering structural parts. For example, the structural parts of some oil platforms use 7075 aluminum plates.
7075 aluminum sheet plate for ship
In addition to the above fields, 7075 aluminum sheet can also be used in the manufacture of sports equipment, building materials, medical equipment, etc. For example, some high-end bicycle frames and medical equipment frames use 7075 aluminum plates to improve the strength and corrosion resistance of the products.
Two of the most popular aluminum sheets for structural applications are 6061 and 7075 aluminum sheets, but they have many differences.
6061 aluminum has a higher silicon content, while 7075 alloy has a higher zinc content. 7075 has a slightly higher magnesium content and more copper.
6061 aluminum sheet
Both 6061 aluminum sheet and 7075 aluminum sheets can be heat treated. The tensile strength of 7075-T6 is almost twice that of 6061-T6. The shear strength of 7075-T6 is about 1.5 times that of 6061-T6.
6061 is solderable, while 7075 is generally considered non-solderable. For 6061 aluminum, heat treatment and aging treatment are required after welding to restore the welded area to its original T state. 7075 is easy to crack after welding.
They have many fields of application, but the parts of application are not the same. For example, in the aerospace industry, 7075 is more likely to be used for gears or rods, while 6061 is more likely to be used in more malleable areas.
3A21 aluminum plate is an Al-Mn series aluminum alloy, which belongs to the weldable LF21 aluminum alloy and is known for its excellent anti-rust properties.
