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.
