Titanium Ti-13V-11Cr-3Al vs Ti-15-3
Titanium · grade comparison
Titanium Ti-13V-11Cr-3Al and Ti-15-3 are both titanium grades. Ti-13V-11Cr-3Al is the stronger of the two: yield strength 860 MPa (125 ksi) against 790 MPa (115 ksi) for Ti-15-3, about 9% more; tensile strength follows at 930 MPa (135 ksi) vs 820 MPa (119 ksi). In exchange, Ti-15-3 is the more ductile: elongation 20% versus 16% for Ti-13V-11Cr-3Al, and Ti-13V-11Cr-3Al is harder (300 HB vs 265 HB). Ti-13V-11Cr-3Al is stiffer (102 GPa vs 82 GPa). On the shop floor, Ti-15-3 welds better (very good vs good) and Ti-13V-11Cr-3Al sits in a lower cost tier (high, $$$$) than Ti-15-3 (specialty, $$$$$).
Ti-13V-11Cr-3AlChoose it when strength drives the design, or when cost is the deciding factor.
Ti-15-3Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
Ti-13V-11Cr-3Al vs Ti-15-3: 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.
