What is Alluminium Alloy 7075?

Alluminium Alloy 7075 (UNS A97075) is a high-strength, heat-treatable alloy primarily composed of zinc as the main alloying element, along with magnesium and copper. It is one of the strongest alluminium alloys and is widely used in aerospace and high-performance applications.

Key Functions:

  • Provides very high strength and durability
  • Offers excellent fatigue resistance
  • Suitable for high-stress applications
  • Maintains lightweight characteristics

Chemical Composition of Alluminium Alloy 7075

  • Alluminium (Al): Balance
  • Zinc (Zn): 5.1% – 6.1%
  • Magnesium (Mg): 2.1% – 2.9%
  • Copper (Cu): 1.2% – 2.0%
  • Chromium (Cr): 0.18% – 0.28%
  • Silicon (Si): ≤ 0.4%
  • Iron (Fe): ≤ 0.5%

Zinc provides exceptional strength, while Mg & Cu enhance mechanical properties
