🔩 Premium CWSR GR9 Titanium Tube – Ti-3Al-2.5V Seamless Tubing for Aerospace Use
📌 Introduction to CWSR GR9 Titanium Tube
The Premium CWSR GR9 Titanium Tube is a specialized seamless tubing product made from Grade 9 titanium alloy (Ti-3Al-2.5V). Designed to meet the highest performance standards in aerospace, industrial, and sporting applications, this tubing is cold worked and stress relieved (CWSR) to achieve a superior combination of strength, flexibility, and corrosion resistance.
With a high strength-to-weight ratio, exceptional corrosion resistance, and reliable weldability, the CWSR GR9 titanium tube is the go-to choice for engineers and manufacturers working in environments where performance cannot be compromised.

🔬 Alloy Composition: Ti-3Al-2.5V (Grade 9)
Grade 9 titanium is a near-alpha alloy composed of approximately 3% Aluminum and 2.5% Vanadium. This composition strikes a perfect balance between strength, formability, and corrosion resistance.
| Element | Content (%) |
| Titanium (Ti) | Balance |
| Aluminum (Al) | 2.5 – 3.5 |
| Vanadium (V) | 2.0 – 3.0 |
| Iron (Fe) | ≤ 0.25 |
| Oxygen (O) | ≤ 0.15 |
| Carbon (C) | ≤ 0.08 |
| Nitrogen (N) | ≤ 0.03 |
| Hydrogen (H) | ≤ 0.015 |
🚀 Why Choose CWSR GR9 Titanium Tube?
✅ High Strength-to-Weight Ratio
Compared to steel or aluminum tubing, CWSR GR9 titanium tubes offer the same strength at nearly half the weight. This makes them ideal for aerospace, racing, and weight-sensitive structures.
✅ Excellent Corrosion Resistance
GR9 titanium tubes are highly resistant to chloride, seawater, and acid corrosion, making them a reliable choice for marine and chemical industries.
✅ Superior Formability
Thanks to the cold worked and stress relieved structure, these tubes offer improved ductility and allow for easier forming and bending operations without cracking.
✅ Weldability
Ti-3Al-2.5V exhibits better weldability than many titanium alloys, and post-weld strength recovery is excellent. CWSR GR9 titanium tubes are often used in welded assemblies without compromising mechanical integrity.
