Titanium Ti-6Al-2Sn-4Zr-6Mo vs Ti-6Al-6V-2Sn
Titanium · grade comparison
Titanium Ti-6Al-2Sn-4Zr-6Mo and Ti-6Al-6V-2Sn are both titanium grades. Ti-6Al-2Sn-4Zr-6Mo is the stronger of the two: yield strength 1,100 MPa (160 ksi) against 980 MPa (142 ksi) for Ti-6Al-6V-2Sn, about 12% more; tensile strength follows at 1,170 MPa (170 ksi) vs 1,050 MPa (152 ksi). In exchange, Ti-6Al-6V-2Sn is the more ductile: elongation 14% versus 10% for Ti-6Al-2Sn-4Zr-6Mo, and Ti-6Al-2Sn-4Zr-6Mo is harder (38 HRC vs 36 HRC). Ti-6Al-2Sn-4Zr-6Mo runs hotter in service (400°C vs 315°C continuous).
Ti-6Al-2Sn-4Zr-6MoChoose it when strength drives the design, or when the part sees heat.
Ti-6Al-6V-2SnChoose it when the part is bent, formed or impact-loaded.
Ti-6Al-2Sn-4Zr-6Mo vs Ti-6Al-6V-2Sn: 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-2Sn-4Zr-6Mo vs Ti-6Al-6V-2Sn — frequently asked
Is Ti-6Al-2Sn-4Zr-6Mo stronger than Ti-6Al-6V-2Sn?
Yes. Ti-6Al-2Sn-4Zr-6Mo has a typical yield strength of 1,100 MPa (160 ksi) against 980 MPa (142 ksi) for Ti-6Al-6V-2Sn — about 12% more. Tensile strength is 1,170 MPa (170 ksi) vs 1,050 MPa (152 ksi).
Which is cheaper, Ti-6Al-2Sn-4Zr-6Mo or Ti-6Al-6V-2Sn?
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-6Al-2Sn-4Zr-6Mo or Ti-6Al-6V-2Sn?
Ti-6Al-6V-2Sn. Its weldability rates fair (35/100) against poor (30/100) for Ti-6Al-2Sn-4Zr-6Mo.
