Titanium B817 Type I vs Ti-6Al-4V (AM, F2924)
Titanium · grade comparison
Titanium B817 Type I and Ti-6Al-4V (AM, F2924) are both titanium grades. Ti-6Al-4V (AM, F2924) is the stronger of the two: yield strength 1,040 MPa (151 ksi) against 350 MPa (50.8 ksi) for B817 Type I, about 197% more; tensile strength follows at 1,150 MPa (167 ksi) vs 450 MPa (65.3 ksi). In exchange, B817 Type I is the more ductile: elongation 18% versus 11% for Ti-6Al-4V (AM, F2924), and Ti-6Al-4V (AM, F2924) is harder (340 HB vs 160 HB). Ti-6Al-4V (AM, F2924) is stiffer (113 GPa vs 100 GPa) and Ti-6Al-4V (AM, F2924) runs hotter in service (350°C vs 300°C continuous). On the shop floor, B817 Type I machines more easily (fair vs poor) and B817 Type I welds better (very good vs good).

B817 Type I vs Ti-6Al-4V (AM, F2924): 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.

B817 Type I vs Ti-6Al-4V (AM, F2924) — frequently asked
Is Ti-6Al-4V (AM, F2924) stronger than B817 Type I?
Yes. Ti-6Al-4V (AM, F2924) has a typical yield strength of 1,040 MPa (151 ksi) against 350 MPa (50.8 ksi) for B817 Type I — about 197% more. Tensile strength is 1,150 MPa (167 ksi) vs 450 MPa (65.3 ksi).
Which is cheaper, B817 Type I or Ti-6Al-4V (AM, F2924)?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, B817 Type I or Ti-6Al-4V (AM, F2924)?
B817 Type I. Its machinability rates fair (35/100) against poor (18/100) for Ti-6Al-4V (AM, F2924); for welding the order is B817 Type I first (very good, 75/100) then Ti-6Al-4V (AM, F2924) (good, 65/100).
