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.
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.
These forgings are widely utilized in industries that prioritize high strength-to-weight ratios and excellent resistance to stress corrosion. In aerospace, they are essential for structural components like wing skins, fuselage frames, bulkheads, and landing gear parts. The defense industry uses them in missile structures and high-performance military equipment. Additionally, Aluminium 7050 forgings are found in automotive racing components, marine fittings, and high-pressure hydraulic systems. Their remarkable machinability, fatigue resistance, and durability make them the go-to choice for critical applications that demand reliability, precision, and long-lasting performance in extreme operating conditions.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
