Titanium Ti Grade 26-ANN vs Ti Grade 26 CWSR
Titanium · Ti Grade 26 temper comparison
Ti Grade 26-ANN and Ti Grade 26 CWSR are two conditions of the same titanium grade, Ti Grade 26: ANN (annealed) versus CWSR (cold worked and stress relieved). The chemistry is identical, so every difference below comes from the condition. Ti Grade 26 CWSR is the stronger of the two: yield strength 520 MPa (75.4 ksi) against 330 MPa (47.9 ksi) for Ti Grade 26-ANN, about 58% more; tensile strength follows at 600 MPa (87 ksi) vs 430 MPa (62.4 ksi). In exchange, Ti Grade 26-ANN is the more ductile: elongation 24% versus 15% for Ti Grade 26 CWSR, and Ti Grade 26 CWSR is harder (210 HB vs 160 HB). Ti Grade 26-ANN runs hotter in service (300°C vs 250°C continuous).
Ti Grade 26-ANNChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Ti Grade 26 CWSRChoose it when strength drives the design.
Ti Grade 26-ANN vs Ti Grade 26 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.

Ti Grade 26-ANN vs Ti Grade 26 CWSR — frequently asked
Is Ti Grade 26 CWSR stronger than Ti Grade 26-ANN?
Yes. Ti Grade 26 CWSR has a typical yield strength of 520 MPa (75.4 ksi) against 330 MPa (47.9 ksi) for Ti Grade 26-ANN — about 58% more. Tensile strength is 600 MPa (87 ksi) vs 430 MPa (62.4 ksi).
Which condition does FabDigit quote by default, ANN or CWSR?
ANN is the default Ti Grade 26 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 26-ANN or Ti Grade 26 CWSR?
Ti Grade 26 CWSR, by a small margin. Both rate fair for machinability — 40/100 against 35/100 for Ti Grade 26-ANN; for welding the order is Ti Grade 26-ANN first (excellent, 90/100) then Ti Grade 26 CWSR (excellent, 85/100).
