Application of 7050 aluminum forgings

Application of 7050 T74 aluminum forgings

This type of aerospace aluminum forgings has high strength, excellent corrosion resistance and fatigue performance, and is commonly used to manufacture aircraft fuselages, wing-fuselage structures, wing frames, as well as spacecraft and missiles.

Application of 7050 T7452 aluminum forgings

Compared to T74 type, this type of aerospace aluminum forgings has better plasticity and toughness, and is usually used to manufacture structural components that require high strength, corrosion resistance and fatigue performance, such as aircraft wings, flaps, control surfaces, etc.
