Titanium Ti Grade 3-ANN vs Ti Grade 3-CW
Titanium · Ti Grade 3 temper comparison
Ti Grade 3-ANN and Ti Grade 3-CW are two conditions of the same titanium grade, Ti Grade 3: ANN (annealed) versus CW (cold worked). The chemistry is identical, so every difference below comes from the condition. Ti Grade 3-CW is the stronger of the two: yield strength 550 MPa (79.8 ksi) against 420 MPa (60.9 ksi) for Ti Grade 3-ANN, about 31% more; tensile strength follows at 620 MPa (89.9 ksi) vs 500 MPa (72.5 ksi). In exchange, Ti Grade 3-ANN is the more ductile: elongation 20% versus 14% for Ti Grade 3-CW, and Ti Grade 3-CW is harder (240 HB vs 200 HB).
Ti Grade 3-ANNChoose it when the part is bent, formed or impact-loaded.
Ti Grade 3-CWChoose it when strength drives the design.
Ti Grade 3-ANN vs Ti Grade 3-CW: 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.
