As a premier titanium alloy tube manufacturer and supplier in China, Daxun Alloy delivers high-quality Grade 5 titanium tubes globally, earning accolades from numerous projects.

Ti 6Al-4V (Grade 5 Titanium) is the most widely adopted titanium alloy, accounting for over half of all titanium usage. Typically used in the annealed state, it withstands temperatures up to 400°C (750°F) and is welded with matching or ELI filler wire. This alloy provides significantly higher strength compared to commercially pure titanium tubes while offering better stiffness and thermal properties (excluding thermal conductivity). The thermal conductivity of Grade 5 titanium tube is about 60% lower than that of CP titanium. Notably, it is heat treatable, allowing for optimal strength and performance. The advantages of Grade 5 titanium seamless tubes include excellent formability, low density, and superior corrosion resistance.

Grade 5 titanium offers an ideal blend of strength, corrosion resistance, weldability, and machinability, making it suitable for a wide array of applications including military aircraft, aerospace components, precision-guided systems, armor, naval equipment, military vacuum apparatus, and more. The closely related 6-4ELI variant is also used in surgical implants. Typically utilized in environments up to 400°C, it delivers improved ductility and toughness in cold working conditions. With excellent specific strength, it is usually provided in an annealed state and can be heat treated to enhance strength for diverse applications. Ti 6Al-4V titanium seamless tubes exhibit a broad spectrum of desirable properties across temperatures from -210°C to 400°C, combining high strength, toughness, and superior welding and processing characteristics.
