As a leading manufacturer and supplier of titanium alloy tubes in China, Daxun Alloy provides premium-quality Grade 5 titanium pipes globally, earning commendations from numerous projects.

Ti 6Al-4V (Grade 5 Titanium) is the most widely used titanium alloy, accounting for over 50% of total titanium usage. Typically used in the annealed state, it operates efficiently at temperatures up to 400°C (750°F). Ti 6Al/4V is welded with matching or ELI filler wire, boasting significantly higher strength than commercial pure titanium tubes while offering superior stiffness and thermal properties, though with lower thermal conductivity. It can be heat treated for enhanced strength and performance. The Grade 5 titanium seamless tube's benefits include excellent formability, low density, and outstanding corrosion resistance.

This grade perfectly blends strength, corrosion resistance, weldability, and machinability, making it ideal for military aircraft, aviation industry, rocket parts, precision-guided components, armor parts, ship equipment, and military vacuum equipment. The 6-4ELI variant is also used in surgical implants. It performs optimally in applications up to 400°C, offering improved ductility and toughness in cold working conditions. Often provided in an annealed state, it is easily heat-treated to enhance strength for various applications. Ti 6Al-4V titanium seamless tube showcases a versatile range of desirable properties across temperatures from -210°C to 400°C, making it the foremost commercialized titanium alloy with excellent welding and processing characteristics.
