Titanium Ti-6Al-6V-2Sn vs VT14
Titanium · grade comparison
Titanium Ti-6Al-6V-2Sn and VT14 are both titanium grades. Ti-6Al-6V-2Sn is the stronger of the two: yield strength 980 MPa (142 ksi) against 850 MPa (123 ksi) for VT14, about 15% more; tensile strength follows at 1,050 MPa (152 ksi) vs 930 MPa (135 ksi). Ti-6Al-6V-2Sn is the more ductile: elongation 14% versus 12% for VT14, and Ti-6Al-6V-2Sn is harder (340 HB vs 285 HB). VT14 runs hotter in service (400°C vs 315°C continuous) and VT14 conducts heat better (8.4 W/m·K vs 6.6 W/m·K). On the shop floor, VT14 welds better (very good vs fair).
Ti-6Al-6V-2SnChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
VT14Choose it when the part sees heat, or when it will be welded.
Ti-6Al-6V-2Sn vs VT14: 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-6Al-6V-2Sn vs VT14 — frequently asked
Is Ti-6Al-6V-2Sn stronger than VT14?
Yes. Ti-6Al-6V-2Sn has a typical yield strength of 980 MPa (142 ksi) against 850 MPa (123 ksi) for VT14 — about 15% more. Tensile strength is 1,050 MPa (152 ksi) vs 930 MPa (135 ksi).
Which is cheaper, Ti-6Al-6V-2Sn or VT14?
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 is easier to machine, Ti-6Al-6V-2Sn or VT14?
VT14, by a small margin. Both rate poor for machinability — 22/100 against 17/100 for Ti-6Al-6V-2Sn; for welding the order is VT14 first (very good, 70/100) then Ti-6Al-6V-2Sn (fair, 35/100).
