Titanium Ti-13V-11Cr-3Al vs Ti-8Mo-8V-2Fe-3Al
Titanium · grade comparison
Titanium Ti-13V-11Cr-3Al and Ti-8Mo-8V-2Fe-3Al are both titanium grades. Ti-8Mo-8V-2Fe-3Al is the stronger of the two: yield strength 1,240 MPa (180 ksi) against 860 MPa (125 ksi) for Ti-13V-11Cr-3Al, about 44% more; tensile strength follows at 1,300 MPa (189 ksi) vs 930 MPa (135 ksi). In exchange, Ti-13V-11Cr-3Al is the more ductile: elongation 16% versus 8% for Ti-8Mo-8V-2Fe-3Al, and Ti-8Mo-8V-2Fe-3Al is harder (370 HB vs 300 HB). Ti-8Mo-8V-2Fe-3Al is stiffer (110 GPa vs 102 GPa) and Ti-8Mo-8V-2Fe-3Al runs hotter in service (315°C vs 260°C continuous). On the shop floor, Ti-13V-11Cr-3Al welds better (good vs fair).
Ti-13V-11Cr-3AlChoose it when the part is bent, formed or impact-loaded, or when it will be welded.
Ti-8Mo-8V-2Fe-3AlChoose it when strength drives the design, or when the part sees heat.
Ti-13V-11Cr-3Al vs Ti-8Mo-8V-2Fe-3Al: 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-8Mo-8V-2Fe-3Al — frequently asked
Is Ti-8Mo-8V-2Fe-3Al stronger than Ti-13V-11Cr-3Al?
Yes. Ti-8Mo-8V-2Fe-3Al has a typical yield strength of 1,240 MPa (180 ksi) against 860 MPa (125 ksi) for Ti-13V-11Cr-3Al — about 44% more. Tensile strength is 1,300 MPa (189 ksi) vs 930 MPa (135 ksi).
Which is cheaper, Ti-13V-11Cr-3Al or Ti-8Mo-8V-2Fe-3Al?
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-8Mo-8V-2Fe-3Al?
Ti-13V-11Cr-3Al. Its weldability rates good (55/100) against fair (35/100) for Ti-8Mo-8V-2Fe-3Al.
