Grade 4 CP-Ti
"Highest strength among CP titanium grades"
Alpha-Beta Alloy
Workhorse alloys balancing strength, toughness, and weldability.
Grade 12 Ti-0.3Mo-0.8Ni
Grade 23 Ti-6Al-4V ELI
"Superior fracture toughness (KIC) compared to standard Grade 5"
Grade 5 Ti-6Al-4V
"Best combination of strength, weight, and corrosion resistance among titanium alloys"
Grade 9 Ti-3Al-2.5V
"Excellent cold formability — superior to Grade 5 (Ti-6Al-4V)"

Titanium Alloy Class Quick-Reference
Compare the six metallurgical classes by tensile strength, density, weldability, and typical applications.
| Alloy Class | Example Grades | Tensile Strength | Density | Weldability | Best for |
|---|---|---|---|---|---|
| Commercially Pure | Grade 1, 2, 3, 4 | 240-550 MPa | 4.51 g/cm3 | Excellent | Best for chemical processing, marine hardware |
| Alpha-Beta | Grade 5, 5 ELI, 9, 23 | 895-1100 MPa | 4.43 g/cm3 | Good (Grade 9) | Best for aerospace structural, medical implants |
| Near-Alpha | Grade 6, Ti-6242 | 895-1100 MPa | 4.55 g/cm3 | Limited | Best for high-temperature jet engine components |
| Beta | Ti-10V-2Fe-3Al, Beta-C | 1100-1400 MPa | 4.65 g/cm3 | Good | Best for high-strength fasteners and springs |
| Intermetallic | Gamma TiAl | 500-800 MPa | 3.9-4.0 g/cm3 | Poor | Best for turbine blades |
| Shape Memory | Nitinol Ni-Ti | 800-1500 MPa | 6.45 g/cm3 | Limited | Best for medical stents and actuators |
How to Select the Right Titanium Alloy
-
Step 1: Identify Operating Environment
Match your service conditions to the alloy class. Seawater, chlorides, and oxidizing acids favor Commercially Pure Grade 2 or Pd-stabilized Grade 7. High-temperature jet engine service above 315 degrees Celsius needs Near-Alpha Grade 6 or Ti-6242. Body-temperature medical implants call for Grade 23 ELI per ASTM F136.
-
Step 2: Define Strength and Density Targets
For aerospace structural parts requiring the best strength-to-weight ratio, Grade 5 Ti-6Al-4V at 895 MPa minimum tensile and 4.43 g/cm3 density remains the industry default. Beta alloys such as Ti-10V-2Fe-3Al reach 1400 MPa for landing gear and fastener applications where maximum strength outweighs density concerns.
-
Step 3: Specify Certification Requirements
Aerospace programs require EN 10204 Type 3.1 mill certification, AS9102 first-article inspection, and full heat-number traceability per ASTM E415. Medical implants add ASTM F136 or ISO 5832-3 compliance, ISO 10993 biocompatibility, and DFARS-compliant Country of Origin. Oil and gas sour service specifies NACE MR0175.
