Daxun Alloy, a premier titanium alloy tube manufacturer and supplier in China, delivers top-quality Grade 5 titanium pipes globally, earning acclaim from numerous projects.

Ti 6Al-4V (Grade 5 Titanium) is the most widely utilized titanium alloy tube, representing over 50% of all titanium usage. Typically used in the annealed state, it functions at temperatures up to 400°C (750°F). Ti 6Al-4V is welded with matching or ELI filler wire. This alloy offers significantly higher strength than commercial pure titanium, coupled with enhanced stiffness and improved thermal properties (excluding thermal conductivity). The thermal conductivity of Grade 5 titanium is about 60% lower than CP titanium. Among its many advantages, it can be heat treated for superior strength and performance. Grade 5 titanium seamless tubes are prized for their strong formability, low density, and exceptional 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.
