What is Titanium Grade 9?
Titanium Grade 9 (Ti-3Al-2.5V) is a near-alpha titanium alloy that offers an excellent balance of strength, ductility, and corrosion resistance with improved formability and weldability compared to Grade 5. This alloy contains 3% aluminum and 2.5% vanadium, providing enhanced cold formability while maintaining good strength characteristics. Its versatile properties make it particularly suitable for aerospace, marine, and industrial applications requiring both strength and fabricability.

Types of Titanium Grade 9 Pipes & Tubes
As premier manufacturers in the industry, we specialize in producing both titanium Grade 9 seamless pipes & tubes and titanium Grade 9 welded pipes & tubes, offering comprehensive solutions for applications requiring optimal balance of strength, formability, and corrosion resistance.
Manufactured from Ti-3Al-2.5V alloy billets through precision cold working processes, these pipes deliver excellent strength-to-weight ratio combined with superior cold formability and weldability. Seamless construction eliminates weld seams, making them the preferred choice for critical aerospace hydraulic systems, aircraft tubing, bicycle frames, and marine applications where optimal balance of strength, formability, and corrosion resistance is required under demanding service conditions.
These pipes provide an economical solution with excellent mechanical properties and enhanced formability across various sizes and dimensions. Welded pipes excel in aerospace components, chemical processing equipment, heat exchangers, and sports equipment where good strength, excellent weldability, and corrosion resistance are essential. Their cost-effectiveness combined with superior fabricability makes them ideal for applications requiring complex forming operations and reliable welded joints in corrosive environments.
