Stainless Shapes supplies titanium 3Al-2.5V to engineers, fabricators, and procurement teams who need a titanium alloy that balances strength, weldability, and cold formability.

Whether your project calls for tubing, sheet, or bar stock, titanium 3Al-2.5V delivers properties that pure titanium can’t match, without the forming limitations that come with higher-strength grades like Ti-6Al-4V.

If you’ve been searching for a reliable source of titanium 3Al-2.5V and haven’t had luck finding the right form or quantity, that’s exactly the kind of hard-to-find request we specialize in solving.

Titanium 3Al-2.5V, also known as titanium grade 9, is an alpha-beta titanium alloy composed of approximately 3% aluminum and 2.5% vanadium. It’s also referred to as Ti-3Al-2.5V, Ti-3-2.5, or by its material standard designation, ASTM B348 Grade 9.

This alloy was developed to solve a specific problem: Ti-6Al-4V, while strong, doesn’t cold form well, and that makes it a poor fit for seamless tubing production. Titanium 3Al-2.5V fills that gap. It sits between commercially pure titanium and Ti-6Al-4V in overall strength, offering properties roughly 30 to 50 percent higher than pure titanium while retaining the cold formability needed to manufacture tubing efficiently.

Key characteristics of titanium 3Al-2.5V include:

• Good strength-to-weight ratio. Titanium 3Al-2.5V is significantly lighter than stainless steel while still offering solid mechanical performance, which matters in any weight-sensitive application.
• Excellent cold formability. Unlike Ti-6Al-4V, this alloy can be cold worked and cold rolled, making it well suited to tubing and other formed shapes.
• Good weldability. Ti-3Al-2.5V welds well using standard gas tungsten arc welding (GTAW/TIG) with proper inert gas shielding, using similar machine settings to those used for stainless steel.
• Solid corrosion resistance. Like most titanium alloys, 3Al-2.5V resists corrosion well in oxidizing and mildly reducing environments, including seawater exposure.
• Strengthening through cold work. While it isn’t typically strengthened through the same aging heat treatments used on other titanium alloys, titanium 3Al-2.5V gains strength through cold working, and can also be solution heat treated and stress relieved depending on the application.

Titanium 3Al-2.5V is commonly identified by its UNS designation R56320, and it’s the alloy of choice whenever a project needs more strength than commercially pure titanium but can’t accommodate the forming limitations of higher-alloyed grades. It’s one of several grades available through our titanium alloys inventory, alongside Grade 2 and Grade 5.

Stainless Shapes stocks titanium 3Al-2.5V in the forms that fabricators and engineers actually need:

• Titanium 3Al-2.5V bar is available for machining, structural applications, and any project requiring solid stock in round or other bar configurations. Bar stock in this grade offers a practical balance of strength and machinability for components that don’t require the extreme strength of Ti-6Al-4V.
• Titanium 3Al-2.5V sheet is stocked for fabrication, forming, and applications where flat stock needs to be cut, formed, or welded into a finished part. The alloy’s cold formability makes it a strong choice for sheet metal applications where complex shapes are required.
• Titanium 3Al-2.5V tubing is where this alloy really shines. It was originally developed for tubing and foil applications, and it remains the go-to titanium alloy for seamless tubing used in aircraft ducting, hydraulic lines, and similar applications where both strength and formability matter.

Across all forms, we work with you to confirm the exact size, condition, and certifications your project requires before material ships. If you’re not sure which form or size fits your application, our sales team can help you narrow it down and track down hard-to-find sizes when needed.

Titanium 3Al-2.5V has a long track record in aerospace, and for good reason. Aircraft and spacecraft components demand a difficult combination of properties: high strength, low weight, and the ability to be formed into complex, often thin-walled shapes. Few materials hit that combination as well as this alloy.

Weight savings without sacrificing strength. Titanium alloys generally offer a much better strength-to-weight ratio than stainless steel, and titanium 3Al-2.5V is no exception. For hydraulic tubing, ducting, and other weight-critical components, that difference adds up across an entire aircraft.

Formability for complex tubing runs. Aircraft hydraulic and pneumatic systems require tubing that can be bent, formed, and routed through tight spaces. Titanium 3Al-2.5V’s cold formability makes it possible to manufacture that tubing without the cracking or forming failures that can occur with higher-strength titanium alloys.

Reliable weldability. Aerospace tubing systems often require field welding or repair. Titanium 3Al-2.5V’s good weldability, using standard GTAW processes with proper inert gas shielding, makes it practical to fabricate and maintain in real-world aerospace manufacturing and MRO environments.

Proven performance history. This isn’t a new or unproven alloy. Titanium 3Al-2.5V has decades of documented use in aircraft ducting, hydraulic systems, and other aerospace applications, giving engineers confidence in its long-term performance.

Corrosion resistance for demanding environments. Aerospace components are exposed to a wide range of environmental stresses, from altitude and temperature swings to ground-level moisture and chemical exposure. Titanium 3Al-2.5V’s inherent corrosion resistance reduces the risk of degradation over the life of the part.

Beyond aerospace, this same combination of properties makes titanium 3Al-2.5V a strong fit for other demanding applications, including marine hardware and even sporting goods like bicycle frames and golf club shafts, anywhere a project needs strength, low weight, and formability in one material.

Choosing the right titanium alloy comes down to matching material properties to your application’s demands. Here’s how titanium 3Al-2.5V compares to the other grades we supply:

Titanium 3Al-2.5V vs. commercially pure titanium (Grade 2). Grade 2 offers the best corrosion resistance and ductility among common titanium grades, along with the lowest strength. Titanium 3Al-2.5V offers meaningfully higher strength, roughly 30 to 50 percent above pure titanium, while still retaining good formability and weldability. If your application needs more strength than Grade 2 can provide but doesn’t require the highest-strength option, 3Al-2.5V is the logical step up.

Titanium 3Al-2.5V vs. Ti-6Al-4V (Grade 5). Ti-6Al-4V is the most widely used titanium alloy and offers substantially higher strength than titanium 3Al-2.5V. However, that added strength comes at the cost of cold formability. Ti-6Al-4V is difficult to cold form into tubing and complex shapes, which is exactly the limitation titanium 3Al-2.5V was developed to solve. When your project needs seamless tubing, tight bends, or other cold-formed shapes, titanium 3Al-2.5V is often the more practical choice, even though it doesn’t match Ti-6Al-4V’s peak strength.

Titanium 3Al-2.5V vs. stainless steel grades. Compared to precipitation-hardening stainless steels like 17-4 PH or austenitic grades like 304 and 316, titanium 3Al-2.5V offers a significant weight advantage. It weighs roughly 43 percent less than comparable stainless steel, while still providing solid strength and corrosion resistance. For weight-critical applications where stainless steel’s strength isn’t strictly necessary, titanium 3Al-2.5V can be the better engineering choice.

The right alloy always depends on your specific application, and our sales team can help you weigh strength, formability, weight, and cost to land on the right material for your project.
