Aluminum 7050
Aluminum 7050 is a high-strength, heat-treatable aluminum alloy developed for demanding aerospace applications where strength, durability, and resistance to stress corrosion cracking are critical. It’s particularly well suited for thick plate and forged components, where consistent mechanical performance through the cross section is required.
Compared to Aluminum 7075, Aluminum 7050 offers improved resistance to stress corrosion cracking and better performance in heavy sections, making it a preferred choice for large structural aerospace components. While its ultimate tensile strength is slightly lower than 7075, its enhanced corrosion resistance and stability often make it the better option for long-term service in demanding environments.
Aluminum 7050 is commonly supplied in plate and forging forms, and is frequently machined into structural aircraft components, bulkheads, and high-load parts where reliability and material integrity are essential.
Tech Steel & Materials supplies Aluminum 7050 with full material traceability and certifications, along with value-added services such as cutting, machining support, and specialized packaging to meet aerospace and defense program requirements.
Aluminum 7050 FAQ
What is Aluminum 7050 used for?
Aluminum 7050 is primarily used in aerospace applications for large structural components where high strength and resistance to stress corrosion cracking are required.
Is Aluminum 7050 stronger than 7075?
Aluminum 7075 generally offers slightly higher ultimate strength, but Aluminum 7050 provides better performance in thick sections and improved resistance to stress corrosion cracking.
Why is Aluminum 7050 preferred for thick plate?
Aluminum 7050 maintains more consistent mechanical properties through thick cross sections, reducing the risk of stress corrosion cracking compared to some other high-strength aluminum alloys.
Is Aluminum 7050 weldable?
Like other high-strength aluminum alloys in this series, Aluminum 7050 is not typically recommended for welding, as welding can negatively affect mechanical properties.
Is Aluminum 7050 heat treatable?
Yes. Aluminum 7050 is a heat-treatable alloy, and its properties are achieved through controlled heat treatment and aging processes.
