Titanium Grade 2 vs Ti Grade 35
Titanium · grade comparison
Titanium Grade 2 and Ti Grade 35 are both titanium grades. Ti Grade 35 is the stronger of the two: yield strength 920 MPa (133 ksi) against 380 MPa (55.1 ksi) for Grade 2, about 142% more; tensile strength follows at 990 MPa (144 ksi) vs 440 MPa (63.8 ksi). In exchange, Grade 2 is the more ductile: elongation 28% versus 16% for Ti Grade 35, and Ti Grade 35 is harder (315 HB vs 150 HB). Ti Grade 35 is stiffer (110 GPa vs 103 GPa) and Ti Grade 35 runs hotter in service (350°C vs 300°C continuous). On the shop floor, Grade 2 machines more easily (fair vs poor), Grade 2 welds better (excellent vs very good), and Ti Grade 35 sits in a lower cost tier (high, $$$$) than Grade 2 (specialty, $$$$$).
Grade 2Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
Ti Grade 35Choose it when strength drives the design, or when the part sees heat.
Grade 2 vs Ti Grade 35: 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 2 vs Ti Grade 35 — frequently asked
Is Ti Grade 35 stronger than Grade 2?
Yes. Ti Grade 35 has a typical yield strength of 920 MPa (133 ksi) against 380 MPa (55.1 ksi) for Grade 2 — about 142% more. Tensile strength is 990 MPa (144 ksi) vs 440 MPa (63.8 ksi).
Which is cheaper, Grade 2 or Ti Grade 35?
Ti Grade 35 is the lower-cost material: it sits in the high tier ($$$$) while Grade 2 is specialty ($$$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which is easier to machine, Grade 2 or Ti Grade 35?
Grade 2. Its machinability rates fair (40/100) against poor (18/100) for Ti Grade 35; for welding the order is Grade 2 first (excellent, 90/100) then Ti Grade 35 (very good, 70/100).
