As a premier titanium alloy tube manufacturer and supplier in China, Daxun Alloy offers high-quality Grade 5 titanium pipes internationally, earning acclaim from numerous projects.

Ti 6Al-4V (Grade 5 Titanium) is the most utilized titanium alloy, representing over 50% of total titanium usage. Typically employed in the annealed state, it can operate at temperatures up to 400°C (750°F). Ti 6Al/4V is welded using matching or ELI filler wire, providing significantly higher strength than commercially pure titanium tubes. It boasts better stiffness and thermal properties (excluding thermal conductivity), with thermal conductivity about 60% lower than CP titanium. Heat treatment enhances its strength and performance, while qualities like strong formability, low density, and excellent corrosion resistance make it ideal for various applications.

This grade perfectly balances strength, corrosion resistance, weldability, and machinability. Widely used in military aircraft, aviation industry, rocket components, precision-guided systems, armor parts, naval equipment, and military vacuum equipment, it is also suitable for surgical implants in its 6-4ELI variant. Typically used up to 400°C, it improves ductility and toughness in cold working conditions. With high specific strength, it is generally provided in the annealed state and can be heat-treated for increased strength, making it suitable for diverse applications. Ti 6Al-4V titanium seamless tube excels with its combination of high strength and toughness, along with excellent welding and processing characteristics.
