Refractory Metal E110 vs Zr 704C
Refractory Metal · grade comparison
Refractory Metal E110 and Zr 704C are both refractory metal grades. Zr 704C is the stronger of the two: yield strength 300 MPa (43.5 ksi) against 255 MPa (37 ksi) for E110, about 18% more; tensile strength follows at 450 MPa (65.3 ksi) vs 390 MPa (56.6 ksi). In exchange, E110 is the more ductile: elongation 30% versus 13% for Zr 704C, and Zr 704C is harder (190 HB vs 155 HB). E110 conducts heat better (17.5 W/m·K vs 13 W/m·K).

E110 vs Zr 704C: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all refractory metal 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.

E110 vs Zr 704C — frequently asked
Is Zr 704C stronger than E110?
Yes. Zr 704C has a typical yield strength of 300 MPa (43.5 ksi) against 255 MPa (37 ksi) for E110 — about 18% more. Tensile strength is 450 MPa (65.3 ksi) vs 390 MPa (56.6 ksi).
Which is cheaper, E110 or Zr 704C?
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, E110 or Zr 704C?
E110. Its weldability rates very good (70/100) against good (65/100) for Zr 704C.
