Titanium Ti Grade 25 Annealed vs Ti Grade 25 Beta Annealed
Titanium · Ti Grade 25 temper comparison
Ti Grade 25 Annealed and Ti Grade 25 Beta Annealed are two conditions of the same titanium grade, Ti Grade 25: Annealed versus Beta Annealed (above beta transus anneal, slow cooled). The chemistry is identical, so every difference below comes from the condition. Both yield at about 880 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (Annealed versus above beta transus anneal, slow cooled). Ti Grade 25 Annealed is the more ductile: elongation 14% versus 10% for Ti Grade 25 Beta Annealed.

Ti Grade 25 Annealed vs Ti Grade 25 Beta Annealed: 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.
