Titanium Ti Grade 11-ANN vs Ti Grade 11-CW
Titanium · Ti Grade 11 temper comparison
Ti Grade 11-ANN and Ti Grade 11-CW are two conditions of the same titanium grade, Ti Grade 11: ANN (annealed) versus CW (cold worked). The chemistry is identical, so every difference below comes from the condition. Ti Grade 11-CW is the stronger of the two: yield strength 410 MPa (59.5 ksi) against 210 MPa (30.5 ksi) for Ti Grade 11-ANN, about 95% more; tensile strength follows at 480 MPa (69.6 ksi) vs 300 MPa (43.5 ksi). In exchange, Ti Grade 11-ANN is the more ductile: elongation 32% versus 15% for Ti Grade 11-CW, and Ti Grade 11-CW is harder (200 HB vs 120 HB). Ti Grade 11-ANN runs hotter in service (300°C vs 250°C continuous).
Ti Grade 11-ANNChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Ti Grade 11-CWChoose it when strength drives the design.
Ti Grade 11-ANN vs Ti Grade 11-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.

Ti Grade 11-ANN vs Ti Grade 11-CW — frequently asked
Is Ti Grade 11-CW stronger than Ti Grade 11-ANN?
Yes. Ti Grade 11-CW has a typical yield strength of 410 MPa (59.5 ksi) against 210 MPa (30.5 ksi) for Ti Grade 11-ANN — about 95% more. Tensile strength is 480 MPa (69.6 ksi) vs 300 MPa (43.5 ksi).
Which condition does FabDigit quote by default, ANN or CW?
ANN is the default Ti Grade 11 condition in the FabDigit quote flow. The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which is easier to machine, Ti Grade 11-ANN or Ti Grade 11-CW?
Ti Grade 11-CW, by a small margin. Both rate fair for machinability — 45/100 against 38/100 for Ti Grade 11-ANN; for welding the order is Ti Grade 11-ANN first (excellent, 90/100) then Ti Grade 11-CW (excellent, 85/100).
