Titanium Grade 11 Annealed vs Grade 11 CW-SR
Titanium · Grade 11 temper comparison
Grade 11 Annealed and Grade 11 CW-SR are two conditions of the same titanium grade, Grade 11: Annealed versus CW-SR (cold worked + stress relieved). The chemistry is identical, so every difference below comes from the condition. Grade 11 CW-SR is the stronger of the two: yield strength 370 MPa (53.7 ksi) against 220 MPa (31.9 ksi) for Grade 11 Annealed, about 68% more; tensile strength follows at 450 MPa (65.3 ksi) vs 330 MPa (47.9 ksi). In exchange, Grade 11 Annealed is the more ductile: elongation 30% versus 18% for Grade 11 CW-SR, and Grade 11 CW-SR is harder (160 HB vs 120 HB). Grade 11 Annealed runs hotter in service (300°C vs 250°C continuous). On the shop floor, Grade 11 CW-SR machines more easily (good vs fair).
Grade 11 AnnealedChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Grade 11 CW-SRChoose it when strength drives the design, or when the part is machined in volume.
Grade 11 Annealed vs 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.

Grade 11 Annealed vs Grade 11 CW-SR — frequently asked
Is Grade 11 CW-SR stronger than Grade 11 Annealed?
Yes. Grade 11 CW-SR has a typical yield strength of 370 MPa (53.7 ksi) against 220 MPa (31.9 ksi) for Grade 11 Annealed — about 68% more. Tensile strength is 450 MPa (65.3 ksi) vs 330 MPa (47.9 ksi).
Which condition does FabDigit quote by default, Annealed or CW-SR?
Annealed is the default 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, Grade 11 Annealed or Grade 11 CW-SR?
Grade 11 CW-SR. Its machinability rates good (55/100) against fair (45/100) for Grade 11 Annealed; for welding the order is Grade 11 Annealed first (excellent, 92/100) then Grade 11 CW-SR (excellent, 85/100).
