Titanium Ti-6Al-2Sn-4Zr-2Mo-0.1Si vs Ti-8Al-1Mo-1V
Titanium · grade comparison
Titanium Ti-6Al-2Sn-4Zr-2Mo-0.1Si and Ti-8Al-1Mo-1V are both titanium grades. Both yield at about 930 MPa — strength does not separate them. Ti-8Al-1Mo-1V is lighter (4.37 g/cm³ vs 4.54 g/cm³ for Ti-6Al-2Sn-4Zr-2Mo-0.1Si) and Ti-8Al-1Mo-1V is stiffer (124 GPa vs 114 GPa). On the shop floor, Ti-6Al-2Sn-4Zr-2Mo-0.1Si welds better (65 vs 55 out of 100).

Ti-6Al-2Sn-4Zr-2Mo-0.1Si vs Ti-8Al-1Mo-1V: 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-2Mo-0.1Si vs Ti-8Al-1Mo-1V — frequently asked
What is the difference between Ti-6Al-2Sn-4Zr-2Mo-0.1Si and Ti-8Al-1Mo-1V?
Titanium Ti-6Al-2Sn-4Zr-2Mo-0.1Si and Ti-8Al-1Mo-1V are both titanium grades. Both yield at about 930 MPa — strength does not separate them. Ti-8Al-1Mo-1V is lighter (4.37 g/cm³ vs 4.54 g/cm³ for Ti-6Al-2Sn-4Zr-2Mo-0.1Si) and Ti-8Al-1Mo-1V is stiffer (124 GPa vs 114 GPa).
Which is cheaper, Ti-6Al-2Sn-4Zr-2Mo-0.1Si or Ti-8Al-1Mo-1V?
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-2Mo-0.1Si or Ti-8Al-1Mo-1V?
Ti-6Al-2Sn-4Zr-2Mo-0.1Si. Its weldability rates good (65/100) against good (55/100) for Ti-8Al-1Mo-1V.
