Daxun Alloy, as a leading titanium alloy tube manufacturer and supplier in China, provides high-quality Grade 5 titanium pipes to the world and has been well received by many projects.

Ti 6Al-4V (Grade 5 Titanium) is the most widely used of all titanium alloy tubes, accounting for more than 50% of the total titanium usage. It is usually used in the annealed state and has an operating temperature of up to 400°C (750°F). Ti 6Al/4V is welded with matching or ELI filler wire. Ti 6Al/4V has significantly higher strength than commercial pure titanium tubes, while having better stiffness and thermal properties (excluding thermal conductivity), and the thermal conductivity of Grade 5 titanium tube is about 60% lower than CP titanium. Among its many advantages, it can be heat treated. Thus, more ideal strength and performance are obtained. The advantages of using Grade 5 titanium seamless tubes include not only strong formability and low density, but also excellent corrosion resistance.

This grade is a perfect combination of strength, corrosion resistance, weldability and machinability. Therefore, it is widely used, such as in military aircraft or aviation industry, rocket parts, precision-guided components, armor parts, ship equipment, military vacuum equipment and other parts. The close version of 6-4, 6-4ELI, is also used in surgical implants. Typically, it is used in applications up to 400°C to improve ductility and toughness in cold working conditions. It also has excellent specific strength. It is usually provided in the annealed state and is easy to heat treat to increase strength for a variety of applications. As a general-purpose titanium alloy, Ti 6Al-4V titanium seamless tube has a wide range of ideal properties at temperatures around -210°C - 400°C. Grade 5 titanium alloy tube is the most commercialized of all titanium alloys. It combines high strength and toughness. Grade 5 titanium alloy tube has good welding and processing characteristics.
