Titanium Ti Grade 1 Annealed vs Ti Grade 1-CD

Titanium · Ti Grade 1 temper comparison

Ti Grade 1 Annealed and Ti Grade 1-CD are two conditions of the same titanium grade, Ti Grade 1: Annealed versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. Ti Grade 1-CD is the stronger of the two: yield strength 340 MPa (49.3 ksi) against 225 MPa (32.6 ksi) for Ti Grade 1 Annealed, about 51% more; tensile strength follows at 420 MPa (60.9 ksi) vs 310 MPa (45 ksi). In exchange, Ti Grade 1 Annealed is the more ductile: elongation 32% versus 18% for Ti Grade 1-CD, and Ti Grade 1-CD is harder (160 HB vs 120 HB).

Ti Grade 1 AnnealedChoose it when the part is bent, formed or impact-loaded.

Ti Grade 1-CDChoose it when strength drives the design.

Ti Grade 1 Annealed vs Ti Grade 1-CD — frequently asked

Is Ti Grade 1-CD stronger than Ti Grade 1 Annealed?

Yes. Ti Grade 1-CD has a typical yield strength of 340 MPa (49.3 ksi) against 225 MPa (32.6 ksi) for Ti Grade 1 Annealed — about 51% more. Tensile strength is 420 MPa (60.9 ksi) vs 310 MPa (45 ksi).

Which condition does FabDigit quote by default, Annealed or CD?

Annealed is the default Ti Grade 1 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 1 Annealed or Ti Grade 1-CD?

Ti Grade 1-CD, by a small margin. Both rate fair for machinability — 50/100 against 42/100 for Ti Grade 1 Annealed; for welding the order is Ti Grade 1 Annealed first (excellent, 88/100) then Ti Grade 1-CD (very good, 82/100).
