Titanium Grade 3 vs Ti Grade 14
Titanium · grade comparison
Titanium Grade 3 and Ti Grade 14 are both titanium grades. Grade 3 is the stronger of the two: yield strength 420 MPa (60.9 ksi) against 360 MPa (52.2 ksi) for Ti Grade 14, about 17% more. In exchange, Ti Grade 14 is the more ductile: elongation 25% versus 20% for Grade 3, and Grade 3 is harder (200 HB vs 160 HB). On the shop floor, Ti Grade 14 sits in a lower cost tier (high, $$$$) than Grade 3 (specialty, $$$$$).
Grade 3Choose it when strength drives the design.
Ti Grade 14Choose it when the part is bent, formed or impact-loaded, or when cost is the deciding factor.
Grade 3 vs Ti Grade 14: 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 3 vs Ti Grade 14 — frequently asked
Is Grade 3 stronger than Ti Grade 14?
Yes. Grade 3 has a typical yield strength of 420 MPa (60.9 ksi) against 360 MPa (52.2 ksi) for Ti Grade 14 — about 17% more. Tensile strength is 500 MPa (72.5 ksi) vs 480 MPa (69.6 ksi).
Which is cheaper, Grade 3 or Ti Grade 14?
Ti Grade 14 is the lower-cost material: it sits in the high tier ($$$$) while Grade 3 is specialty ($$$$$). 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 3 over Ti Grade 14?
Pick Grade 3 when strength drives the design. Pick Ti Grade 14 when the part is bent, formed or impact-loaded, or when cost is the deciding factor.
