Why is 7075 aluminum often used to manufacture aircraft and automobile components?

Aug 12, 2025

Aluminum 7075 is one of the most advanced aluminum alloys available today, famous for its outstanding mechanical strength, good load-bearing capacity and light weight. This is the reason why this type of aluminum is widely used in high-performance industries such as aerospace, sports cars, racing cars and military equipment.

Composition and outstanding properties of aluminum 7075

Aluminum 7075 belongs to the group of super-durable aluminum alloys, with main components including aluminum (Al) , zinc (Zn) , and minor elements such as magnesium (Mg), copper (Cu) and chromium (Cr). This combination of components gives 7075 outstanding advantages:

  • High tensile strength (up to 572 MPa), comparable to steel but about 2.8 times lighter.
  • Outstanding fatigue resistance and deformation resistance , especially suitable for parts subject to continuous force.
  • Good corrosion resistance when surface treated with anodizing or protective paint coating.
  • Precision machining is easy, allowing the production of complex parts with tight tolerances.

Why 7075 Aluminum is Popular in the Aviation Industry

In the aviation industry , every gram of weight has a direct impact on flight performance and fuel consumption. Aluminum 7075 meets both requirements: maximum weight reduction and high strength maintenance . Parts such as airframes, landing gear, propellers, and brackets are often made from 7075 thanks to:

  • Light weight , helps reduce load on the engine.
  • Good impact and vibration resistance , ensuring flight safety.
  • Fatigue resistance extends component life.

Applications of 7075 aluminum in the automotive and racing industry

In the motorsports and racing industry , speed and safety go hand in hand. Aluminum 7075 is used to make wheels, drive shafts, suspension systems, chassis thanks to:

  • Reduced overall weight , faster acceleration and fuel economy.
  • Increases chassis rigidity , improving handling.
  • Ensure safety , thanks to good load-bearing capacity and anti-deformation.

Compare 7075 aluminum with other aluminum grades

Compared with popular aluminum alloys such as 6061 or 5052 , aluminum 7075 has:

  • Mechanical strength is 1.5 - 2 times higher .
  • Better machinability and polishing.
  • Disadvantages: Natural corrosion resistance is lower than 5052, but can be completely overcome by surface treatment.
