As China's leading titanium alloy tube manufacturer, Daxun Alloy delivers high-quality Grade 5 titanium pipes globally, receiving acclaim from numerous projects.

Ti 6Al-4V (Grade 5 Titanium) is the most utilized titanium alloy, accounting for over 50% of total titanium usage. Typically annealed, it operates up to 400°C (750°F) and is welded using matching or ELI filler wire. It offers significantly higher strength and better stiffness than commercially pure titanium tubes, although it has about 60% lower thermal conductivity. It is heat treatable for enhanced strength and performance. The advantages include robust formability, low density, and exceptional corrosion resistance.

This grade perfectly balances strength, corrosion resistance, weldability, and machinability. It's extensively used in military aircraft, aviation, rocket parts, precision-guided components, armor, ship equipment, military vacuum equipment, and more. Close variants like 6-4 ELI are used in surgical implants. Used in applications up to 400°C, it enhances ductility and toughness in cold conditions. Typically annealed, it is easy to heat treat for increased strength across various applications. Ti 6Al-4V titanium seamless tube's wide-ranging properties make it ideal at temperatures between -210°C to 400°C. It combines high strength and toughness, with excellent welding and processing characteristics.
