Titanium ERTi-23 vs ERTi-5
Titanium · grade comparison
Titanium ERTi-23 and ERTi-5 are both titanium grades. Both yield at about 860 MPa — strength does not separate them. ERTi-23 is the more ductile: elongation 12% versus 8% for ERTi-5. ERTi-5 runs hotter in service (350°C vs 315°C continuous). On the shop floor, ERTi-23 welds better (excellent vs very good).
ERTi-23Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
ERTi-5Choose it when the part sees heat.
ERTi-23 vs ERTi-5: 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.

ERTi-23 vs ERTi-5 — frequently asked
What is the difference between ERTi-23 and ERTi-5?
Titanium ERTi-23 and ERTi-5 are both titanium grades. Both yield at about 860 MPa — strength does not separate them. ERTi-23 is the more ductile: elongation 12% versus 8% for ERTi-5.
Which is cheaper, ERTi-23 or ERTi-5?
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, ERTi-23 or ERTi-5?
ERTi-23. Its weldability rates excellent (85/100) against very good (70/100) for ERTi-5.
