As a leading manufacturer and supplier in China, Daxun Alloy provides world-class Grade 5 titanium pipes, earning accolades for various projects globally.

Ti 6Al-4V (Grade 5 Titanium) reigns as the most extensively used titanium alloy, representing over 50% of total titanium usage. Typically in an annealed state, it operates up to 400°C (750°F) and is welded with matching or ELI filler wire. Grade 5 titanium boasts significantly higher strength than commercially pure titanium, with superior stiffness and thermal properties (excluding thermal conductivity). The alloy has about 60% lower thermal conductivity than CP titanium. Heat treatment further enhances its strength and performance, offering exceptional formability, low density, and excellent corrosion resistance.

This grade perfectly balances strength, corrosion resistance, weldability, and machinability. It finds extensive use in military aircraft, aviation, rocket parts, precision-guided components, armor parts, ship equipment, and military vacuum equipment. The close variant, 6-4ELI, is used in surgical implants. Typically used up to 400°C, it improves ductility and toughness in cold working conditions, providing excellent specific strength. Supplied in an annealed state, it is easily heat-treated for enhanced strength across various applications. As a versatile titanium alloy, Ti 6Al-4V titanium seamless tube offers an ideal set of properties at temperatures ranging from -210°C to 400°C. Grade 5 titanium alloy tube remains the most commercialized of all titanium alloys, combining high strength and toughness with superior welding and processing characteristics.
