7050 is known as the "flying aluminum" due to its outstanding resistance to stress corrosion cracking and excellent peel resistance. Additionally, 7050 exhibits improved toughness, corrosion resistance, and excellent anodizing performance.Quick Quote
Its low sensitivity to quenching allows 7050 to maintain high-strength performance for extended periods, especially in thicknesses ranging from 3 to 6 inches, surpassing other high-strength alloys.
It is advisable to avoid conventional welding with 7050, as the welding process can compromise the strength of the alloy.Quick Quote

What is the difference between 7050 and 7075?
Alloy 7050 exhibits better toughness/corrosion resistance characteristics than alloy 7075. Because it is less quench sensitive than most aerospace aluminum alloys, 7050 retains its strength properties in thicker sections while maintaining good stress corrosion cracking resistance and fracture toughness levels.
7050 Aluminum: 7050 is known for its combination of high strength and toughness. It has slightly better stress corrosion cracking resistance than 7075.
7075 Aluminum: 7075 is known for its exceptionally high strength-to-weight ratio and is often considered one of the strongest aluminum alloys available. It might not have the same level of toughness as 7050 but is still widely used in applications where high strength is crucial.Quick Quote

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.Quick Quote
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.
To reduce heat treatment stress and prevent quenching deformation
pre-compression should be applied to free forgings after solution treatment and before artificial aging, with a permanent deformation of 1.5%-5.0% to eliminate internal stresses.
The formability of this alloy is similar to that of 7075 aluminum alloy. If the initial forging temperature is too high, hot forging is prone to occur, which is unfavorable for the hammer forging process.Quick Quote
