Titanium Grade 3 vs VT1-0
Titanium · grade comparison
Titanium Grade 3 and VT1-0 are both titanium grades. Grade 3 is the stronger of the two: yield strength 420 MPa (60.9 ksi) against 320 MPa (46.4 ksi) for VT1-0, about 31% more; tensile strength follows at 500 MPa (72.5 ksi) vs 450 MPa (65.3 ksi). In exchange, VT1-0 is the more ductile: elongation 28% versus 20% for Grade 3, and Grade 3 is harder (200 HB vs 155 HB). On the shop floor, VT1-0 sits in a lower cost tier (high, $$$$) than Grade 3 (specialty, $$$$$).
Grade 3Choose it when strength drives the design.
VT1-0Choose it when the part is bent, formed or impact-loaded, or when cost is the deciding factor.
Grade 3 vs VT1-0: 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 VT1-0 — frequently asked
Is Grade 3 stronger than VT1-0?
Yes. Grade 3 has a typical yield strength of 420 MPa (60.9 ksi) against 320 MPa (46.4 ksi) for VT1-0 — about 31% more. Tensile strength is 500 MPa (72.5 ksi) vs 450 MPa (65.3 ksi).
Which is cheaper, Grade 3 or VT1-0?
VT1-0 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 VT1-0?
Pick Grade 3 when strength drives the design. Pick VT1-0 when the part is bent, formed or impact-loaded, or when cost is the deciding factor.
