Titanium Ti-13V-11Cr-3Al vs Ti-15Mo-2.7Nb-3Al-0.2Si
Titanium · grade comparison
Titanium Ti-13V-11Cr-3Al and Ti-15Mo-2.7Nb-3Al-0.2Si are both titanium grades. Ti-13V-11Cr-3Al is the stronger of the two: yield strength 860 MPa (125 ksi) against 810 MPa (117 ksi) for Ti-15Mo-2.7Nb-3Al-0.2Si, about 6% more; tensile strength follows at 930 MPa (135 ksi) vs 840 MPa (122 ksi). In exchange, Ti-15Mo-2.7Nb-3Al-0.2Si is the more ductile: elongation 18% versus 16% for Ti-13V-11Cr-3Al, and Ti-13V-11Cr-3Al is harder (31 HRC vs 28 HRC). Ti-13V-11Cr-3Al is stiffer (102 GPa vs 80 GPa) and Ti-15Mo-2.7Nb-3Al-0.2Si runs hotter in service (480°C vs 260°C continuous).

Ti-13V-11Cr-3Al vs Ti-15Mo-2.7Nb-3Al-0.2Si: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all titanium grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

Ti-13V-11Cr-3Al vs Ti-15Mo-2.7Nb-3Al-0.2Si — frequently asked
Is Ti-13V-11Cr-3Al stronger than Ti-15Mo-2.7Nb-3Al-0.2Si?
Yes. Ti-13V-11Cr-3Al has a typical yield strength of 860 MPa (125 ksi) against 810 MPa (117 ksi) for Ti-15Mo-2.7Nb-3Al-0.2Si — about 6% more. Tensile strength is 930 MPa (135 ksi) vs 840 MPa (122 ksi).
Which is cheaper, Ti-13V-11Cr-3Al or Ti-15Mo-2.7Nb-3Al-0.2Si?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which welds better, Ti-13V-11Cr-3Al or Ti-15Mo-2.7Nb-3Al-0.2Si?
Ti-15Mo-2.7Nb-3Al-0.2Si. Its weldability rates good (60/100) against good (55/100) for Ti-13V-11Cr-3Al.
