Discover different grade of titanium with clear comparisons of properties, applications, and selection tips for engineers and industrial buyers.
You might already know that titanium is the gold standard for high-performance engineering…
But are you confident you’re selecting the right specification?
The difference between Grade 2 und Grade 5 isn’t just a number—it’s the difference between a successful component and a catastrophic failure.
At Vastmaterial, we know that navigating the different grades of titanium can be complex.
That’s why I’ve compiled this technical breakdown.
From the ductility of Commercially Pure (CP) titanium to the high-strength fatigue resistance of Ti-6Al-4V, you’re going to learn exactly how to match the grade to your application.
Let’s get into the data.
The Big Four: Commercially Pure (CP) Titanium Grades
At Vastmaterial, our production of Commercially Pure (CP) Titanium focuses on unalloyed grades ranging from Grade 1 to Grade 4. These grades are distinguished primarily by their oxygen and iron content, which directly influences their mechanical properties while maintaining the superior corrosion resistance titanium is known for. We manufacture these materials in strict compliance with ASTM B348 und ASTM B265 standards to ensure reliability in critical industrial applications.
Grade 1: Softest and Most Ductile
Grade 1 is the purest form of titanium we supply. Because it has the lowest oxygen content, it offers the highest titanium ductility and excellent cold formability. This makes it the ideal choice for applications requiring severe deformation.
- Key Characteristic: Superior impact toughness and high corrosion resistance.
- Common Applications: Deep drawing, explosive bonding, cladding, and plate heat exchangers.
- Formability: Excellent for parts that require extensive shaping without cracking.
Grade 2: The Industry Workhorse
Grade 2 is the most widely used titanium grade in our inventory and the global market. It offers a perfect balance of moderate strength and reasonable ductility, making it the standard specification for most industrial plants.

- cURL Too many subrequests. This is essentially Grade 2 with 0.12% to 0.25% palladium added. This addition makes it the most corrosion-resistant of all titanium alloys, specifically designed for reducing acid environments and high-temperature chemical processing.
- Grade 9 (Ti-3Al-2.5V): Often called “half-6-4,” this grade bridges the gap between Grade 2 and Grade 5. It offers higher strength than CP grades but retains excellent cold formability. It is widely used in hydraulic tubing and high-end bicycle frames.
- Grade 12 (Ti-0.3Mo-0.8Ni): By adding molybdenum and nickel, we create an alloy with superior crevice corrosion resistance and high strength at elevated temperatures, making it ideal for shell and tube heat exchangers and marine components.
Critical Comparison: Grade 2 vs Grade 5
When navigating the cURL Too many subrequests., the decision often comes down to two contenders: Grade 2 (Commercially Pure) and Grade 5 (Ti-6Al-4V). While both offer the signature corrosion resistance titanium is famous for, their mechanical behaviors are distinct. Grade 2 is the industry “workhorse,” favored for its ductility and formability, while Grade 5 is the “ace” for high-strength applications.
Tensile Strength and Yield Strength Data
The most significant differentiator in the Grade 2 titanium vs Grade 5 debate is strength. Grade 5 is an alpha-beta alloy, meaning it is heat-treatable and significantly stronger than commercially pure grades.
Here is a quick breakdown of the mechanical properties based on ASTM B348 standards:
| Eigenschaft | Grade 2 (CP Titanium) | Grade 5 (Ti-6Al-4V) |
|---|---|---|
| cURL Too many subrequests. | ~275 MPa (40 ksi) | ~828 MPa (120 ksi) |
| Zugfestigkeit | ~345 MPa (50 ksi) | ~895 MPa (130 ksi) |
| Ductility (Elongation) | High (~20%) | Moderate (~10%) |
| Härte | Lower (Easier to form) | Higher (Wear resistant) |
Cost and Machinability Differences
Cost and ease of fabrication play a huge role in project budgeting. Because Grade 5 contains expensive alloying elements like Vanadium and Aluminum, it typically commands a higher market price than Grade 2.
- Bearbeitbarkeit: Grade 2 behaves somewhat like stainless steel; it is softer and easier to machine, weld, and cold form. Grade 5, being harder, wears down tools faster and requires slower cutting speeds and higher coolant flow.
- Production Cost: For parts requiring extensive machining or complex shaping, Grade 2 is generally more cost-effective. However, if the part design relies on high strength-to-weight ratios to reduce material volume, Grade 5 can sometimes offset its higher raw material cost.
When to Choose Grade 2 vs Grade 5
Selecting the right material depends entirely on the environmental and mechanical stresses your application faces.
- Choose Grade 2 (CP) If:
- Corrosion Resistance is Priority: Excellent for chemical processing, marine environments, and desalination plants.
- Formability is Key: Ideal for applications requiring extensive welding, bending, or cold forming, such as heat exchangers and piping systems.

Cost Efficiency and Budgeting
Over-specifying is a common mistake that kills project budgets. Sourcing directly from our factory in Baoji allows for cost savings, but selecting the right grade maximizes value.
| Faktor | Recommended Grade | Cost Implication |
|---|---|---|
| cURL Too many subrequests. | Grade 2 | Most Cost-Effective. The “workhorse” grade with high availability. |
| Hohe Festigkeit | Grade 5 | Moderate. Higher processing costs but reduces material weight needed. |
| Extreme Corrosion | cURL Too many subrequests. | High. Contains Palladium, making it expensive but necessary for acidic environments. |
| Tubing/Hydraulics | cURL Too many subrequests. | Moderate to High. Premium for seamless tubing applications. |
If your application does not require the extreme strength of an alloy or the palladium content of Grade 7, sticking to Grade 2 is the smartest financial move. It balances decent strength, excellent corrosion resistance, and the lowest price point among standard titanium options.
