Titanium C-23 vs ZTA15
Titanium · grade comparison
Titanium C-23 and ZTA15 are both titanium grades. Both yield at about 860 MPa — strength does not separate them. C-23 is the more ductile: elongation 12% versus 9% for ZTA15, and C-23 is harder (330 HB vs 310 HB). ZTA15 runs hotter in service (500°C vs 400°C continuous) and ZTA15 conducts heat better (7.5 W/m·K vs 6.7 W/m·K).
C-23Choose it when the part is bent, formed or impact-loaded.
ZTA15Choose it when the part sees heat.
C-23 vs ZTA15: 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.

C-23 vs ZTA15 — frequently asked
What is the difference between C-23 and ZTA15?
Titanium C-23 and ZTA15 are both titanium grades. Both yield at about 860 MPa — strength does not separate them. C-23 is the more ductile: elongation 12% versus 9% for ZTA15, and C-23 is harder (330 HB vs 310 HB).
Which is cheaper, C-23 or ZTA15?
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.
When should I choose C-23 over ZTA15?
Pick C-23 when the part is bent, formed or impact-loaded. Pick ZTA15 when the part sees heat.
