Titanium Ti-6Al-2Nb-1Ta-0.8Mo Annealed vs Ti-6Al-2Nb-1Ta-0.8Mo-AW
Titanium · Ti-6Al-2Nb-1Ta-0.8Mo temper comparison
Ti-6Al-2Nb-1Ta-0.8Mo Annealed and Ti-6Al-2Nb-1Ta-0.8Mo-AW are two conditions of the same titanium grade, Ti-6Al-2Nb-1Ta-0.8Mo: Annealed versus AW (as-welded deposit). The chemistry is identical, so every difference below comes from the condition. Both yield at about 780 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (Annealed versus as-welded deposit). Ti-6Al-2Nb-1Ta-0.8Mo Annealed is the more ductile: elongation 15% versus 10% for Ti-6Al-2Nb-1Ta-0.8Mo-AW.

Ti-6Al-2Nb-1Ta-0.8Mo Annealed vs Ti-6Al-2Nb-1Ta-0.8Mo-AW: 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.
