Titanium Ti-10-2-3 vs Ti-8Mo-8V-2Fe-3Al
Titanium · grade comparison
Titanium Ti-10-2-3 and Ti-8Mo-8V-2Fe-3Al are both titanium grades. Ti-8Mo-8V-2Fe-3Al is the stronger of the two: yield strength 1,240 MPa (180 ksi) against 930 MPa (135 ksi) for Ti-10-2-3, about 33% more; tensile strength follows at 1,300 MPa (189 ksi) vs 1,000 MPa (145 ksi). In exchange, Ti-10-2-3 is the more ductile: elongation 12% versus 8% for Ti-8Mo-8V-2Fe-3Al, and Ti-8Mo-8V-2Fe-3Al is harder (40 HRC vs 32 HRC). Ti-10-2-3 is lighter (4.65 g/cm³ vs 4.9 g/cm³ for Ti-8Mo-8V-2Fe-3Al) and Ti-10-2-3 conducts heat better (7.8 W/m·K vs 6.5 W/m·K). On the shop floor, Ti-8Mo-8V-2Fe-3Al sits in a lower cost tier (high, $$$$) than Ti-10-2-3 (specialty, $$$$$).

Ti-8Mo-8V-2Fe-3AlChoose it when strength drives the design, or when cost is the deciding factor.
Ti-10-2-3 vs Ti-8Mo-8V-2Fe-3Al: 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.
