As a premier titanium alloy tube manufacturer and supplier in China, Daxun Alloy delivers high-quality Grade 5 titanium pipes, acclaimed by numerous projects worldwide.

Ti 6Al-4V (Grade 5 Titanium) is the predominant titanium alloy tube, constituting over 50% of titanium usage. Typically annealed, it functions up to 400°C (750°F) and is welded with matching or ELI filler wire. This alloy boasts higher strength than commercial pure titanium tubes, along with enhanced stiffness and improved thermal properties, except for thermal conductivity, which is about 60% lower than CP titanium. It can be heat-treated for superior strength and performance, offering strong formability, low density, and excellent corrosion resistance.

This grade is a stellar blend of strength, corrosion resistance, weldability, and machinability, making it ideal for military aircraft, aviation, rocket parts, precision-guided components, armor parts, ship equipment, military vacuum equipment, and surgical implants (using 6-4ELI). Operating effectively at -210°C to 400°C, Grade 5 titanium seamlessly combines high strength and toughness with good welding and processing characteristics, making it the most commercialized titanium alloy.
