Ti 10V-2Fe-3Al is a metastable beta titanium alloy designed for forgings. It forges at lower temperature and lower load than the alpha beta alloys, hardens deeply on aging and delivers strength in the 170 to 190 ksi range with good fracture toughness.
That combination made it the material of choice for large forged landing gear and airframe structural components where it replaces heavier steel parts.
Stocked as bar, billet and forgings, supplied solution treated or solution treated and aged.

- Excellent forgeability and deep hardenability
- Substantial weight saving over steel in landing gear structure
- Property level adjustable through aging
Nominal chemistry
Percent by weight, nominal composition per the governing specification. The mill test report for your heat is the controlling document.
Typical mechanical properties
| Condition | Tensile strength | Yield strength | Elongation | Hardness |

- Airframe structural fittings
- Actuator and linkage components
- Springs
Fabrication notes
Machining
Titanium runs at low surface speed with heavy positive feed, sharp tooling, rigid fixturing and high volume coolant. Dwelling glazes the surface and work hardens it. Chips are combustible, so manage swarf. We can supply rough machined, saw cut, waterjet or near net blanks to cut down the metal removed.
Welding
Readily weldable by GTAW, plasma, electron beam and laser processes with full inert gas shielding of the pool, root and cooling weld. Contamination shows up as colour on the bead and as embrittlement, so shielding and cleanliness govern the result.
Forming
Cold formability is limited compared with steel, so hot forming, generous bend radii and stress relief after forming are normal practice. Surfaces must be clean of iron pickup before heat treatment.

What is Ti 10V-2Fe-3Al?
Ti 10V-2Fe-3Al is a metastable beta titanium alloy designed for forgings. It forges at lower temperature and lower load than the alpha beta alloys, hardens deeply on aging and delivers strength in the 170 to 190 ksi range with good fracture toughness.
What forms is Ti 10V-2Fe-3Al available in?
We supply Ti 10V-2Fe-3Al in bar, sheet, plate, forging. Custom sizes are converted from billet, and we can provide saw cut, waterjet or near net blanks so material arrives closer to your finished part.
What is the UNS or equivalent designation for Ti 10V-2Fe-3Al?
Ti 10V-2Fe-3Al is designated UNS R56410. If your drawing calls out an obsolete or foreign designation we can cross reference it and confirm the equivalent before you order.
What specifications can Ti 10V-2Fe-3Al be supplied to?
Commonly ordered specifications include AMS 4983, AMS 4984, AMS 4986, AMS 4987, UNS R56410. Material is released to the specification and condition on your purchase order, with mill test reports supplied as standard.
What conditions can Ti 10V-2Fe-3Al be ordered in?
We can supply Solution treated, Solution treated and aged. If our stock is not already in the condition you need, we can quote it with the heat treatment performed before shipment.
Can you cut Ti 10V-2Fe-3Al to size?
Yes. Saw cutting, waterjet, laser and shearing are available, along with trepanning, gun drilling, lathe turning and CNC machining, so you can order blanks or rough machined pieces rather than full lengths.
Do you provide test reports and additional testing on Ti 10V-2Fe-3Al?
Every order ships with mill test reports and heat traceability. If your print calls for ultrasonic inspection, penetrant dye, magnetic particle, chemical assay, micrography, hardness or mechanical testing and our stock does not already carry it, we can quote the material with that work performed.
Can Ti 10V-2Fe-3Al be supplied to DFARS domestic melt requirements?
Tell us at quote stage if the order is DFARS or domestic melt restricted and we will confirm availability against that requirement before you commit.
What do you need to quote Ti 10V-2Fe-3Al?
Grade, form, dimensions, quantity, specification and condition, plus any testing or certification requirements and the date you need it. Send a drawing if you have one. Quotes are typically ready within 24 hours.
How does Ti 10V-2Fe-3Al compare with Ti 6Al-4V?
