What is Aluminium 7050 Forgings?

Aluminium 7050 has ~6.2–7.2% zinc, ~2.0–2.6% magnesium, ~2.0–2.6% copper, trace chromium and other stabilizers. In the T7451 or T7651 temper, tensile strength is ~560–600 MPa, yield strength ~500–540 MPa, with elongation ~10–15%. High hardness. Density ~2.83 g/cm³. Very good fatigue strength, fracture toughness, and resistance to stress-corrosion cracking. Forging of the microstructure refines it, enhancing toughness and mechanical homogeneity.

Frequently Asked Questions (FAQ)

Can Aluminum 7050 be forged into shapes with tight tolerances?

Yes, Aluminum 7050 can be forged into shapes with tight tolerances, as it offers good strength and machinability. However, precise control over temperature and pressure is required for optimal results.

Can Aluminum 7050 be used for high-temperature forging applications?

Aluminum 7050 is not ideal for high-temperature forging applications due to its limited heat resistance. It is better suited for aerospace and structural applications, offering good strength at lower temperatures.

What are the advantages of using Aluminum 7050 for custom forgings?

Aluminum 7050 offers high strength, excellent resistance to stress corrosion cracking, and good fatigue resistance. It's ideal for aerospace and military applications, providing superior performance in custom forgings.

Aluminium 7050 Forgings Uses

7050 forgings are employed widely in aerospace structural components — wing spars, fuselage frames, bulkheads, and landing gear connectors. They are selected for major stress-carrying joints in aircraft and helicopters. In the defense industry, they’re employed for missile casings, aerospace structural components, and high-strength connectors. Also in motorsport and high-performance vehicles where strength-to-weight is critical. In heavily loaded frames or structural subassemblies, 7050 forgings are used in place of regular alloys. Due to their resistance to fatigue and corrosion, they are best used in harsh structural applications.
