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 risk of corrosion.

Characteristics

• This alloy of European origin has properties similar to that of American grade 7050.
For all over-aged T74 and T76 conditions it achieves a balance between mechanical properties (strength, toughness, fatigue) and resistance to stress corrosion.
