Titanium Ti-17 vs Ti-6Al-2Sn-4Zr-6Mo
Titanium · grade comparison
Titanium Ti-17 and Ti-6Al-2Sn-4Zr-6Mo are both titanium grades. Both yield at about 1,075 MPa — strength does not separate them. Ti-6Al-2Sn-4Zr-6Mo runs hotter in service (400°C vs 350°C continuous).

Ti-17 vs Ti-6Al-2Sn-4Zr-6Mo: 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-17 vs Ti-6Al-2Sn-4Zr-6Mo — frequently asked
What is the difference between Ti-17 and Ti-6Al-2Sn-4Zr-6Mo?
Titanium Ti-17 and Ti-6Al-2Sn-4Zr-6Mo are both titanium grades. Both yield at about 1,075 MPa — strength does not separate them. Ti-6Al-2Sn-4Zr-6Mo runs hotter in service (400°C vs 350°C continuous).
Which is cheaper, Ti-17 or Ti-6Al-2Sn-4Zr-6Mo?
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.
When should I choose Ti-17 over Ti-6Al-2Sn-4Zr-6Mo?
Pick Ti-6Al-2Sn-4Zr-6Mo when the part sees heat.
