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.

Characteristics

• 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.
