Titanium Ti Grade 1-CD vs Ti Grade 1-CR
Titanium · Ti Grade 1 temper comparison
Ti Grade 1-CD and Ti Grade 1-CR are two conditions of the same titanium grade, Ti Grade 1: CD (cold drawn) versus CR (cold rolled). The chemistry is identical, so every difference below comes from the condition. Ti Grade 1-CR is the stronger of the two: yield strength 400 MPa (58 ksi) against 340 MPa (49.3 ksi) for Ti Grade 1-CD, about 18% more; tensile strength follows at 480 MPa (69.6 ksi) vs 420 MPa (60.9 ksi). In exchange, Ti Grade 1-CD is the more ductile: elongation 18% versus 10% for Ti Grade 1-CR, and Ti Grade 1-CR is harder (180 HB vs 160 HB). Ti Grade 1-CD runs hotter in service (300°C vs 250°C continuous).
Ti Grade 1-CDChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Ti Grade 1-CRChoose it when strength drives the design.
Ti Grade 1-CD vs Ti Grade 1-CR: 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 1-CD vs Ti Grade 1-CR — frequently asked
Is Ti Grade 1-CR stronger than Ti Grade 1-CD?
Yes. Ti Grade 1-CR has a typical yield strength of 400 MPa (58 ksi) against 340 MPa (49.3 ksi) for Ti Grade 1-CD — about 18% more. Tensile strength is 480 MPa (69.6 ksi) vs 420 MPa (60.9 ksi).
Which condition does FabDigit quote by default, CD or CR?
Annealed is the default Ti Grade 1 condition in the FabDigit quote flow (neither CD nor CR). 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.
When should I choose Ti Grade 1-CD over Ti Grade 1-CR?
Pick Ti Grade 1-CD when the part is bent, formed or impact-loaded, or when the part sees heat. Pick Ti Grade 1-CR when strength drives the design.
