Titanium C-1 vs Grade C-2
Titanium · grade comparison
Titanium C-1 and Grade C-2 are both titanium grades. Grade C-2 is the stronger of the two: yield strength 385 MPa (55.8 ksi) against 210 MPa (30.5 ksi) for C-1, about 83% more; tensile strength follows at 480 MPa (69.6 ksi) vs 300 MPa (43.5 ksi). In exchange, C-1 is the more ductile: elongation 20% versus 16% for Grade C-2, and Grade C-2 is harder (205 HB vs 120 HB). C-1 conducts electricity better (3.6 % IACS vs 3.1 % IACS).
C-1Choose it when the part is bent, formed or impact-loaded.
Grade C-2Choose it when strength drives the design.
C-1 vs Grade C-2: 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.

C-1 vs Grade C-2 — frequently asked
Is Grade C-2 stronger than C-1?
Yes. Grade C-2 has a typical yield strength of 385 MPa (55.8 ksi) against 210 MPa (30.5 ksi) for C-1 — about 83% more. Tensile strength is 480 MPa (69.6 ksi) vs 300 MPa (43.5 ksi).
Which is cheaper, C-1 or Grade C-2?
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, C-1 or Grade C-2?
C-1, by a small margin. Both rate fair for machinability — 42/100 against 35/100 for Grade C-2.
