Titanium Grade 9 vs Ti-6-22-22
Titanium · grade comparison
Titanium Grade 9 and Ti-6-22-22 are both titanium grades. Ti-6-22-22 is the stronger of the two: yield strength 1,160 MPa (168 ksi) against 570 MPa (82.7 ksi) for Grade 9, about 104% more; tensile strength follows at 1,240 MPa (180 ksi) vs 690 MPa (100 ksi). In exchange, Grade 9 is the more ductile: elongation 20% versus 10% for Ti-6-22-22, and Ti-6-22-22 is harder (38 HRC vs 24 HRC). Grade 9 is lighter (4.48 g/cm³ vs 4.65 g/cm³ for Ti-6-22-22) and Ti-6-22-22 is stiffer (117 GPa vs 100 GPa). On the shop floor, Grade 9 machines more easily (28 vs 16 out of 100) and Grade 9 welds better (very good vs fair).
Grade 9Choose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
Ti-6-22-22Choose it when strength drives the design.
Grade 9 vs Ti-6-22-22: 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 9 vs Ti-6-22-22 — frequently asked
Is Ti-6-22-22 stronger than Grade 9?
Yes. Ti-6-22-22 has a typical yield strength of 1,160 MPa (168 ksi) against 570 MPa (82.7 ksi) for Grade 9 — about 104% more. Tensile strength is 1,240 MPa (180 ksi) vs 690 MPa (100 ksi).
Which is cheaper, Grade 9 or Ti-6-22-22?
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 9 or Ti-6-22-22?
Grade 9, by a small margin. Both rate poor for machinability — 28/100 against 16/100 for Ti-6-22-22; for welding the order is Grade 9 first (very good, 80/100) then Ti-6-22-22 (fair, 45/100).
