As a premier manufacturer and supplier, Daxun Alloy provides high-quality Grade 5 Titanium Pipes globally, acclaimed by many engineering projects.

Ti 6Al-4V (Grade 5 Titanium) is the most utilized titanium alloy tube, accounting for over 50% of total titanium usage. It is commonly used in an annealed state with an operating temperature up to 400°C (750°F), employing matching or ELI filler wire for welding. It offers higher strength than commercial pure titanium tubes with improved stiffness and thermal properties (excluding thermal conductivity). Grade 5 titanium has about 60% lower thermal conductivity than CP titanium, can be heat-treated for enhanced performance, and boasts excellent formability, low density, and superior corrosion resistance.

This grade perfectly combines strength, corrosion resistance, weldability, and machinability. Widely used in military aircraft and aviation, rocket parts, precision-guided components, armor parts, ship equipment, military vacuum equipment, and surgical implants like 6-4ELI. Suitable for temperatures up to 400°C, it greatly improves ductility and toughness in cold working conditions. Typically provided in the annealed state, it is easily heat-treated for increased strength across various applications. Ti 6Al-4V titanium seamless tube offers a versatile range of properties from -210°C to 400°C, making it the most commercialized titanium alloy, excelling in strength and toughness with superb welding and processing characteristics.
