Titanium Grade 23 vs Ti-5Al-2.5Fe
Titanium · grade comparison
Titanium Grade 23 and Ti-5Al-2.5Fe are both titanium grades. Both yield at about 850 MPa — strength does not separate them. Grade 23 is harder — 340 HV against 320 HV for Ti-5Al-2.5Fe — which matters for wear surfaces and threads. Grade 23 runs hotter in service (350°C vs 300°C continuous). On the shop floor, Grade 23 welds better (very good vs good).
Grade 23Choose it when surface hardness matters, or when the part sees heat.
Grade 23 vs Ti-5Al-2.5Fe: 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 23 vs Ti-5Al-2.5Fe — frequently asked
What is the difference between Grade 23 and Ti-5Al-2.5Fe?
Titanium Grade 23 and Ti-5Al-2.5Fe are both titanium grades. Both yield at about 850 MPa — strength does not separate them. Grade 23 is harder — 340 HV against 320 HV for Ti-5Al-2.5Fe — which matters for wear surfaces and threads.
Which is cheaper, Grade 23 or Ti-5Al-2.5Fe?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which welds better, Grade 23 or Ti-5Al-2.5Fe?
Grade 23. Its weldability rates very good (80/100) against good (65/100) for Ti-5Al-2.5Fe.
