Titanium Grade 1 vs Ti Grade 37
Titanium · grade comparison
Titanium Grade 1 and Ti Grade 37 are both titanium grades. Ti Grade 37 is the stronger of the two: yield strength 350 MPa (50.8 ksi) against 220 MPa (31.9 ksi) for Grade 1, about 59% more; tensile strength follows at 450 MPa (65.3 ksi) vs 300 MPa (43.5 ksi). In exchange, Grade 1 is the more ductile: elongation 30% versus 25% for Ti Grade 37, and Ti Grade 37 is harder (170 HB vs 120 HB). Grade 1 conducts heat better (20 W/m·K vs 17 W/m·K). On the shop floor, Grade 1 machines more easily (fair vs poor) and Ti Grade 37 sits in a lower cost tier (high, $$$$) than Grade 1 (specialty, $$$$$).
Grade 1Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
Ti Grade 37Choose it when strength drives the design, or when cost is the deciding factor.
Grade 1 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.
