Titanium Grade 2 vs Ti Grade 36
Titanium · grade comparison
Titanium Grade 2 and Ti Grade 36 are both titanium grades. Grade 2 is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 340 MPa (49.3 ksi) for Ti Grade 36, about 12% more. Grade 2 is the more ductile: elongation 28% versus 25% for Ti Grade 36, and Grade 2 is harder (150 HB vs 138 HB). Grade 2 is lighter (4.51 g/cm³ vs 5.7 g/cm³ for Ti Grade 36) and Grade 2 is stiffer (103 GPa vs 62 GPa). On the shop floor, Grade 2 machines more easily (fair vs poor), Grade 2 welds better (excellent vs very good), and Ti Grade 36 sits in a lower cost tier (high, $$$$) than Grade 2 (specialty, $$$$$).
Grade 2Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
Ti Grade 36Choose it when cost is the deciding factor.
Grade 2 vs Ti Grade 36: 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 36 — frequently asked
Is Grade 2 stronger than Ti Grade 36?
Yes. Grade 2 has a typical yield strength of 380 MPa (55.1 ksi) against 340 MPa (49.3 ksi) for Ti Grade 36 — about 12% more. Tensile strength is 440 MPa (63.8 ksi) vs 420 MPa (60.9 ksi).
Which is cheaper, Grade 2 or Ti Grade 36?
Ti Grade 36 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 36?
Grade 2. Its machinability rates fair (40/100) against poor (25/100) for Ti Grade 36; for welding the order is Grade 2 first (excellent, 90/100) then Ti Grade 36 (very good, 80/100).
