Titanium Grade 1 vs Grade 11
Titanium · grade comparison
Titanium Grade 1 and Grade 11 are both titanium grades. Grade 11 is the stronger of the two: tensile strength 330 MPa (47.9 ksi) against 300 MPa (43.5 ksi) for Grade 1, about 10% more. Grade 1 conducts heat better (20 W/m·K vs 16.5 W/m·K). On the shop floor, Grade 11 forms better (excellent vs very good) and Grade 11 sits in a lower cost tier (high, $$$$) than Grade 1 (specialty, $$$$$).
Grade 11Choose it when strength drives the design, or when cost is the deciding factor.
Grade 1 vs Grade 11: 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 1 vs Grade 11 — frequently asked
Is Grade 11 stronger than Grade 1?
Yes. Grade 11 has a typical tensile strength of 330 MPa (47.9 ksi) against 300 MPa (43.5 ksi) for Grade 1 — about 10% more.
Which is cheaper, Grade 1 or Grade 11?
Grade 11 is the lower-cost material: it sits in the high tier ($$$$) while Grade 1 is specialty ($$$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
When should I choose Grade 1 over Grade 11?
Pick Grade 11 when strength drives the design, or when cost is the deciding factor.
