Daxun Alloy, as a leading titanium alloy tube manufacturer and supplier in China, provides high-quality Grade 5 titanium pipes to the world and has been well received by many projects.

Ti 6Al-4V (Grade 5 Titanium) is the most widely used of all titanium alloy tubes, accounting for more than 50% of the total titanium usage. It is usually used in the annealed state and has an operating temperature of up to 400°C (750°F). Ti 6Al/4V is welded with matching or ELI filler wire. Ti 6Al/4V has significantly higher strength than commercial pure titanium tubes, while having better stiffness and thermal properties (excluding thermal conductivity), and the thermal conductivity of Grade 5 titanium tube is about 60% lower than CP titanium. Among its many advantages, it can be heat treated. Thus, more ideal strength and performance are obtained. The advantages of using Grade 5 titanium seamless tubes include not only strong formability and low density, but also excellent corrosion resistance.

This grade is a perfect combination of strength, corrosion resistance, weldability and machinability. Therefore, it is widely used, such as in military aircraft or aviation industry, rocket parts, precision-guided components, armor parts, ship equipment, military vacuum equipment and other parts. The close version of 6-4, 6-4ELI, is also used in surgical implants. Typically, it is used in applications up to 400°C to improve ductility and toughness in cold working conditions. It also has excellent specific strength. It is usually provided in the annealed state and is easy to heat treat to increase strength for a variety of applications. As a general-purpose titanium alloy, Ti 6Al-4V titanium seamless tube has a wide range of ideal properties at temperatures around -210°C - 400°C. Grade 5 titanium alloy tube is the most commercialized of all titanium alloys. It combines high strength and toughness. Grade 5 titanium alloy tube has good welding and processing characteristics.

WELDABILITY

• The DAXUN Ti-6Al-4V Grade 5 Alloy Titanium Tube exhibits exceptional weldability in either the annealed or solution and partially aged states, with ageing incorporated during post-weld heat treatment.
• It is crucial to take precautions to prevent contamination by oxygen, nitrogen, and hydrogen. Fusion welding should be carried out in an inert gas-filled chamber or with an inert gas tail shield to protect the molten metal and surrounding hot zone. Additionally, spot welding, seam welding, and flash welding can be performed without requiring a protective environment, ensuring versatile application.

SPECIAL PRECAUTIONS

• The DAXUN Ti-6Al-4V, Grade 5 alloy is susceptible to contamination by hydrogen through improper pickling and by absorption of oxygen, nitrogen, and carbon during processes such as forging, heat treatment, and brazing. Such contamination can diminish ductility, negatively affecting notch sensitivity and forming properties, necessitating stringent control measures.
