Titanium Ti-10-2-3 vs Ti-3Al-8V-6Cr-4Mo-4Zr
Titanium · grade comparison
Titanium Ti-10-2-3 and Ti-3Al-8V-6Cr-4Mo-4Zr are both titanium grades. Ti-10-2-3 is the stronger of the two: yield strength 930 MPa (135 ksi) against 850 MPa (123 ksi) for Ti-3Al-8V-6Cr-4Mo-4Zr, about 9% more; tensile strength follows at 1,000 MPa (145 ksi) vs 900 MPa (131 ksi). In exchange, Ti-3Al-8V-6Cr-4Mo-4Zr is the more ductile: elongation 18% versus 12% for Ti-10-2-3. Ti-10-2-3 is lighter (4.65 g/cm³ vs 4.82 g/cm³ for Ti-3Al-8V-6Cr-4Mo-4Zr) and Ti-10-2-3 is stiffer (110 GPa vs 86 GPa). On the shop floor, Ti-3Al-8V-6Cr-4Mo-4Zr welds better (good vs fair) and Ti-3Al-8V-6Cr-4Mo-4Zr sits in a lower cost tier (high, $$$$) than Ti-10-2-3 (specialty, $$$$$).
Ti-10-2-3Choose it when strength drives the design, or when weight is the constraint.
Ti-3Al-8V-6Cr-4Mo-4ZrChoose it when the part is bent, formed or impact-loaded, or when it will be welded.
Ti-10-2-3 vs Ti-3Al-8V-6Cr-4Mo-4Zr: 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.
