Compare all 4 conditionsHide
| Condition · open for datasheet | Best for | Yield MPa | Tensile MPa | Elong. % | Hardness | Conductivity |
|---|---|---|---|---|---|---|
STDefault Solution annealed | Softest, most formable single-phase beta condition — the state sheet, plate and wire are supplied in for forming, welding and subsequent aging. | 860 | 930 | 16 | 31 HRC | — |
Cold worked | Use when strength must be raised without a thermal cycle — the beta matrix work-hardens heavily and stays ductile enough to form springs and fasteners blanks. | 1,080 | 1,130 | 7 | 36 HRC | 1.2 % IACS |
Solution treated and aged | Pick after forming/welding when 1200 MPa-class strength is required; aging is done on the finished part because ductility drops sharply. | 1,170 | 1,220 | 8 | 40 HRC | — |
Cold worked and aged | Highest strength condition, used for springs, fasteners and thin high-load skins where low ductility and toughness are acceptable. | 1,330 | 1,400 | 4 | 44 HRC | — |
What is Ti-13V-11Cr-3Al?
Ti-13V-11Cr-3Al (UNS R58010, AMS 4917, AMS 4959) is one of the earliest fully beta titanium alloys, strengthened by aging after solution treatment or cold work. Engineers use it where sheet must be formed cold and then aged: typical properties are 860 MPa yield, 930 MPa tensile, 16% elongation, 300 HB (31 HRC), 102 GPa modulus and service to 260 °C. It is historically associated with supersonic airframe skins. Machinability is low (16), the alloy is effectively non-formable once aged, and Ti-15Mo-2.7Nb-3Al-0.2Si is the more common choice for new high-temperature sheet designs. Ti-13V-11Cr-3Al has a density of 4.87 g/cm³ (0.176 lb/in³), heavier than 95% of titanium grades. It melts at 1,427°C (2,601 °F). Ti-13V-11Cr-3Al has a yield strength of 860 MPa (125 ksi) and a tensile strength of 930 MPa (135 ksi) — stronger than 71% of titanium grades. Elongation at break is 16% and the elastic modulus is 102 GPa (14.8 Msi).

Working with Ti-13V-11Cr-3Al
Is Ti-13V-11Cr-3Al easy to machine?
Machine like a hard beta titanium: rigid setups, sharp uncoated-carbide or PVD-coated tools, 15–30 m/min surface speed, heavy flood coolant, positive feed to avoid work hardening; machine before aging where possible.
Can Ti-13V-11Cr-3Al be welded?
GTAW, plasma or EBW under high-purity argon/vacuum with full backside shielding gives ductile single-phase beta welds; post-weld aging strengthens but embrittles the HAZ, so weld in ST condition and age the assembly.
Can Ti-13V-11Cr-3Al be formed, bent or molded?
In the ST condition it cold-forms and roll-forms nearly like austenitic stainless (allow generous springback and 3–4 t bend radii); after aging it is essentially non-formable.

What surface finishes work on Ti-13V-11Cr-3Al?
Descale by molten-salt/HNO₃-HF pickling (control hydrogen pickup), then optional titanium anodize or chemical conversion; hard-facing or ion nitriding is needed for galling contact surfaces.

Ti-13V-11Cr-3Al — frequently asked
What is Ti-13V-11Cr-3Al used for?
Ti-13V-11Cr-3Al is typically used for airframe skins, high-temperature structural sheet and historic supersonic aircraft parts. In short: first production beta titanium; cold-forms then age hardens; 260 °C service capability.
What is the yield strength of Ti-13V-11Cr-3Al?
Ti-13V-11Cr-3Al has a typical yield strength of 860 MPa (125 ksi) and a tensile strength of 930 MPa (135 ksi) — stronger than 71% of titanium grades. Strength varies by condition: see the 4 listed tempers.
Is Ti-13V-11Cr-3Al easy to machine?
Not especially — machinability is rated poor (16/100, worse than 93% of titanium grades).

Can Ti-13V-11Cr-3Al be welded?
Yes — weldability is rated good (55/100). GTAW, plasma or EBW under high-purity argon/vacuum with full backside shielding gives ductile single-phase beta welds; post-weld aging strengthens but embrittles the HAZ, so weld in ST condition and age the assembly.
What surface finishes work on Ti-13V-11Cr-3Al?

What is the maximum service temperature of Ti-13V-11Cr-3Al?
Ti-13V-11Cr-3Al is rated for continuous use to about 260°C (500 °F). Strength falls off well before that limit — check the elevated-temperature data for load-bearing parts.
What is the difference between Ti-13V-11Cr-3Al-ST and Ti-13V-11Cr-3Al-CWA?
ST is the default condition — softest, most formable single-phase beta condition — the state sheet, plate and wire are supplied in for forming, welding and subsequent aging. CWA: highest strength condition, used for springs, fasteners and thin high-load skins where low ductility and toughness are acceptable. Yield strength is 860 MPa in ST versus 1,330 MPa in CWA.
How much does Ti-13V-11Cr-3Al cost?
Ti-13V-11Cr-3Al is a high-cost titanium ($$$$), pricier than about 78% of the materials FabDigit quotes. Part price depends far more on geometry, tolerance and quantity than on the raw stock — upload a CAD file for a live quote.
