Titanium Grade 2 vs Ti Grade 37
Titanium · grade comparison
Titanium Grade 2 and Ti Grade 37 are both titanium grades. Grade 2 is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 350 MPa (50.8 ksi) for Ti Grade 37, about 9% more. Grade 2 is the more ductile: elongation 28% versus 25% for Ti Grade 37, and Ti Grade 37 is harder (170 HB vs 150 HB). On the shop floor, Ti Grade 37 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 37Choose it when cost is the deciding factor.
Grade 2 vs Ti Grade 37: 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.
