Titanium Ti Grade 11-ANN vs Ti Grade 11 CW-SR
Titanium · Ti Grade 11 temper comparison
Ti Grade 11-ANN and Ti Grade 11 CW-SR are two conditions of the same titanium grade, Ti Grade 11: ANN (annealed) versus CW-SR (cold worked and stress relieved). The chemistry is identical, so every difference below comes from the condition. Ti Grade 11 CW-SR is the stronger of the two: yield strength 370 MPa (53.7 ksi) against 210 MPa (30.5 ksi) for Ti Grade 11-ANN, about 76% more; tensile strength follows at 440 MPa (63.8 ksi) vs 300 MPa (43.5 ksi). In exchange, Ti Grade 11-ANN is the more ductile: elongation 32% versus 18% for Ti Grade 11 CW-SR, and Ti Grade 11 CW-SR is harder (178 HB vs 120 HB).

Ti Grade 11-ANN vs Ti Grade 11 CW-SR: 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.
