As a leader in titanium alloy tube manufacturing, Daxun Alloy, based in China, delivers top-tier Grade 5 titanium pipes globally, earning accolades from numerous projects.

Ti 6Al-4V (Grade 5 Titanium) is the most extensively used titanium alloy, accounting for over 50% of total titanium utilization. Typically used in the annealed state, it operates up to 400°C (750°F) and is welded with matching or ELI filler wire. It offers significantly higher strength than commercial pure titanium, with superior stiffness and thermal properties (excluding thermal conductivity). The thermal conductivity of Grade 5 titanium is about 60% lower than CP titanium. Its heat-treatable nature allows for enhanced strength and performance. The seamless tubes boast strong formability, low density, and excellent corrosion resistance.

This grade is an ideal blend of strength, corrosion resistance, weldability, and machinability. It is widely applied in military aircraft, aviation, rocket parts, precision-guided components, armor parts, ship equipment, and military vacuum equipment. The 6-4ELI variant is also employed in surgical implants. Typically used at temperatures up to 400°C, it enhances ductility and toughness in cold working conditions. Grade 5 titanium alloy tubes, provided in the annealed state, can easily be heat treated for increased strength, making them versatile for various applications between -210°C and 400°C. This titanium alloy is the most commercialized, offering a unique combination of high strength and toughness, with excellent welding and processing properties.
