Products Description
Grade 9 Ti-3Al-2.5V titanium alloy tube/pipe is a high-performance, near-alpha titanium alloy engineered to deliver an optimal balance of strength, weldability, and corrosion resistance. Its composition, which includes 3% aluminum (Al), 2.5% vanadium (V), and titanium (Ti) as the base metal, is crucial in bridging the gap between commercially pure titanium (CP grades) and high-strength alloys like Ti-6Al-4V (Grade 5). This unique composition makes it ideal for applications requiring lightweight durability and precision fabrication.
Key Properties:
High Strength-to-Weight Ratio: The Grade 9 Ti-3Al-2.5V titanium alloy tube boasts a tensile strength of 620–860 MPa (90–125 ksi) and yield strength of 480–820 MPa (70–119 ksi), surpassing CP titanium grades while maintaining a density of only 4.48 g/cm³. This exceptional strength-to-weight ratio instills confidence in the product's performance in demanding applications.
Superior Corrosion Resistance: The Grade 9 Ti-3Al-2.5V titanium alloy pipe exhibits exceptional resistance to chlorides, seawater, and acidic environments, making it a reliable choice for marine, chemical, and offshore applications. This superior corrosion resistance ensures the product's durability and longevity, providing a sense of security to the end users.
Enhanced Formability: The Grade 9 titanium alloy tube showcases excellent cold-working and hot-forming capabilities, allowing for seamless tube production and complex geometries. This enhanced formability reassures the audience about the product's adaptability to various fabrication processes, instilling a sense of confidence in its versatility.
Its biocompatibility, meeting ASTM F67/F136 standards, makes it an excellent choice for medical applications. This means it can be safely used in surgical instruments and implantable devices, providing a high level of safety and reliability for patients.
Available Specifications:
Sizes: The outer diameters range from 6 mm to 150 mm, and the wall thicknesses range from 0.5 mm to 10 mm.
Conditions: Annealed (AMS 4943), cold-worked (ASTM B338), or solution-treated.
Surface Finish: Pickled, polished (Ra ≤0.8 μm), or passivated for enhanced corrosion resistance.
Quality Assurance:
Full traceability with Mill Test Certificates (MTC) per EN 10204 3.1.
Non-destructive testing (NDT), including ultrasonic testing (UT) and eddy current inspection.
Compliance with ISO 9001 and AS9100 aerospace quality management systems.
Application Fields:
• Bicycle parts
• All types of exhaust pipes
• Titanium welding head
• Transportation pipeline
