As a leading titanium alloy tube manufacturer and supplier in China, Daxun Alloy provides top-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 global titanium usage. Commonly used in the annealed state, it operates efficiently up to 400°C (750°F) and is welded with matching or ELI filler wire. Ti 6Al/4V offers significantly higher strength and better stiffness compared to commercially pure titanium tubes, though its thermal conductivity is about 60% lower. Its many advantages include heat treatability for enhanced strength and performance. Grade 5 titanium seamless tubes stand out for their formability, low density, and exceptional corrosion resistance.

This grade strikes an ideal balance of strength, corrosion resistance, weldability, and machinability, making it versatile for use in military aircraft, aviation, rocket parts, precision-guided components, armor parts, ship equipment, military vacuum equipment, and more. The 6-4, 6-4ELI variants are also used in surgical implants. Suitable for applications up to 400°C, it ensures improved ductility and toughness in cold working conditions. Delivered typically in the annealed state, it is easily heat-treatable for increased strength across diverse applications. Ti 6Al-4V titanium seamless tubes are the most commercialized titanium alloys, offering a rich blend of high strength, toughness, welding, and processing characteristics.
