7050 T74 T7452 T736 Aerospace Grade Aluminum Forging

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.

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

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.

application of 7050 aerospace aluminum forging

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
