Titanium B817 Type I vs Ti-6Al-4V ELI (Grade 23) AM Powder
Titanium · grade comparison
Titanium B817 Type I and Ti-6Al-4V ELI (Grade 23) AM Powder are both titanium grades. Ti-6Al-4V ELI (Grade 23) AM Powder is the stronger of the two: yield strength 1,010 MPa (146 ksi) against 350 MPa (50.8 ksi) for B817 Type I, about 189% more; tensile strength follows at 1,100 MPa (160 ksi) vs 450 MPa (65.3 ksi). In exchange, B817 Type I is the more ductile: elongation 18% versus 13% for Ti-6Al-4V ELI (Grade 23) AM Powder, and Ti-6Al-4V ELI (Grade 23) AM Powder is harder (330 HB vs 160 HB). Ti-6Al-4V ELI (Grade 23) AM Powder is stiffer (113 GPa vs 100 GPa) and Ti-6Al-4V ELI (Grade 23) AM Powder runs hotter in service (350°C vs 300°C continuous). On the shop floor, B817 Type I machines more easily (fair vs poor).

B817 Type I vs Ti-6Al-4V ELI (Grade 23) AM Powder: 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.
