As a leading manufacturer and supplier in China, Daxun Alloy provides premium Grade 5 titanium pipes globally, earning accolades from numerous projects.

Ti 6Al-4V (Grade 5 Titanium) stands as the most used titanium alloy, representing over 50% of total titanium usage. Typically annealed, it can operate up to 400°C (750°F). Welded with either matching or ELI filler wire, it offers significantly higher strength than commercially pure titanium tubes, along with better stiffness and thermal properties (excluding thermal conductivity). Its thermal conductivity is about 60% lower than CP titanium. One of its many advantages is heat treatability, which enhances strength and performance. Grade 5 titanium seamless tubes boast strong formability, low density, and excellent corrosion resistance.

This grade is the perfect blend of strength, corrosion resistance, weldability, and machinability, widely used in military aircraft, aviation, rocket parts, precision-guided components, armor parts, ship equipment, military vacuum equipment, and surgical implants (6-4, 6-4ELI). Typically used up to 400°C, it enhances ductility and toughness in cold working conditions. With excellent specific strength, it's usually provided in an annealed state and is easily heat treated to boost strength for various applications. As a general-purpose alloy, Ti 6Al-4V titanium seamless tube offers ideal properties at temperatures between -210°C and 400°C. It combines high strength and toughness with commendable welding and processing characteristics.
