Titanium Grade 16 vs Ti-8Al-1Mo-1V
Titanium · grade comparison
Titanium Grade 16 and Ti-8Al-1Mo-1V are both titanium grades. Ti-8Al-1Mo-1V is the stronger of the two: yield strength 950 MPa (138 ksi) against 380 MPa (55.1 ksi) for Grade 16, about 150% more; tensile strength follows at 1,000 MPa (145 ksi) vs 485 MPa (70.3 ksi). In exchange, Grade 16 is the more ductile: elongation 28% versus 15% for Ti-8Al-1Mo-1V, and Ti-8Al-1Mo-1V is harder (315 HB vs 150 HB). Ti-8Al-1Mo-1V is lighter (4.37 g/cm³ vs 4.51 g/cm³ for Grade 16) and Ti-8Al-1Mo-1V is stiffer (124 GPa vs 105 GPa). On the shop floor, Grade 16 machines more easily (fair vs poor) and Grade 16 welds better (excellent vs good).
Grade 16Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
Ti-8Al-1Mo-1VChoose it when strength drives the design, or when weight is the constraint.
Grade 16 vs Ti-8Al-1Mo-1V: 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.

Grade 16 vs Ti-8Al-1Mo-1V — frequently asked
Is Ti-8Al-1Mo-1V stronger than Grade 16?
Yes. Ti-8Al-1Mo-1V has a typical yield strength of 950 MPa (138 ksi) against 380 MPa (55.1 ksi) for Grade 16 — about 150% more. Tensile strength is 1,000 MPa (145 ksi) vs 485 MPa (70.3 ksi).
Which is cheaper, Grade 16 or Ti-8Al-1Mo-1V?
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, Grade 16 or Ti-8Al-1Mo-1V?
Grade 16. Its machinability rates fair (38/100) against poor (18/100) for Ti-8Al-1Mo-1V; for welding the order is Grade 16 first (excellent, 88/100) then Ti-8Al-1Mo-1V (good, 55/100).
