Titanium Ti Grade 2 Annealed vs Ti Grade 2 CW-Hard
Titanium · Ti Grade 2 temper comparison
Ti Grade 2 Annealed and Ti Grade 2 CW-Hard are two conditions of the same titanium grade, Ti Grade 2: Annealed versus CW-Hard (cold worked, as-rolled hard strip/foil). The chemistry is identical, so every difference below comes from the condition. Ti Grade 2 CW-Hard is the stronger of the two: yield strength 630 MPa (91.4 ksi) against 340 MPa (49.3 ksi) for Ti Grade 2 Annealed, about 85% more; tensile strength follows at 700 MPa (102 ksi) vs 440 MPa (63.8 ksi). In exchange, Ti Grade 2 Annealed is the more ductile: elongation 25% versus 8% for Ti Grade 2 CW-Hard, and Ti Grade 2 CW-Hard is harder (230 HB vs 150 HB). Ti Grade 2 Annealed runs hotter in service (300°C vs 200°C continuous).
Ti Grade 2 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Ti Grade 2 CW-HardChoose it when strength drives the design.
Ti Grade 2 Annealed vs Ti Grade 2 CW-Hard: 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.
