Titanium B817 Type II vs Ti-6Al-4V ELI (AM, F3001)
Titanium · grade comparison
Titanium B817 Type II and Ti-6Al-4V ELI (AM, F3001) are both titanium grades. Ti-6Al-4V ELI (AM, F3001) is the stronger of the two: yield strength 990 MPa (144 ksi) against 855 MPa (124 ksi) for B817 Type II, about 16% more; tensile strength follows at 1,080 MPa (157 ksi) vs 930 MPa (135 ksi). On the shop floor, Ti-6Al-4V ELI (AM, F3001) welds better (very good vs good).
Ti-6Al-4V ELI (AM, F3001)Choose it when strength drives the design, or when it will be welded.
B817 Type II vs Ti-6Al-4V ELI (AM, F3001): 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.
