    0,23
  • Al
    Base
  • Cu
    1,6
  • Fe
    2,5
  • Zn
    5,6

Applications

• Forged bars and medium sized openor closed-die forgings, used in the production of structural components for aerospace where high mechanical strength is required.

Mechanical properties

• This alloy achieves a good balance between mechanical properties (strength, toughness and fatigue) and stress corrosion resistance for thicknesses ≤ 100mm.
• As its hardenability is not very high, grades 7010 or 7050 would be preferred where greater thicknesses are involved.

Mechanical features

  • Heat treatment
    T 7352 - T 7354 conditions
  • UTS (N/mm²)
    > 455
  • A (%)
    > 7
  • Solution treated : H
    Annealed : R
  • Thermo-mechanical treatment : TM
    Quenched and tempered : T+RV
  • Sub-zero treatment : F
    Solution treated and aged : T+RV
