Spécifications
- EU Al Zn6CuMgZr
- USA UNS:A97050
Typical composition
- Al Base
- Cu 2,3
- Fe 2,3
- Mg 0,12
- Zn 6,2
Applications
• Closed-die forgings and large forged bars for the aerospace industry.
• This alloy has been specifically designed for structural components subject to high fatigue stress and the risk of corrosion.
Mechanical properties
• This alloy used in the over-aged T74 condition achieves a good balance between mechanical properties (strength, toughness and fatigue) and stress corrosion resistance.
• In the over-aged T76 condition, it is particularly resistant to exfoliation corrosion.
• Its good hardenability makes it suitable for producing thick parts.
