Titanium Ti Grade 16 Annealed vs Ti Grade 16 CWSR
Titanium · Ti Grade 16 temper comparison
Ti Grade 16 Annealed and Ti Grade 16 CWSR are two conditions of the same titanium grade, Ti Grade 16: Annealed versus CWSR (cold worked and stress relieved). The chemistry is identical, so every difference below comes from the condition. Ti Grade 16 CWSR is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 380 MPa (55.1 ksi) for Ti Grade 16 Annealed, about 26% more; tensile strength follows at 560 MPa (81.2 ksi) vs 460 MPa (66.7 ksi). In exchange, Ti Grade 16 Annealed is the more ductile: elongation 26% versus 16% for Ti Grade 16 CWSR, and Ti Grade 16 CWSR is harder (185 HB vs 150 HB). Ti Grade 16 Annealed runs hotter in service (300°C vs 250°C continuous).
Ti Grade 16 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Ti Grade 16 CWSRChoose it when strength drives the design.
Ti Grade 16 Annealed vs Ti Grade 16 CWSR: 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.
