Refractory Metal Zr 705C-ANN vs Zr 705C-F
Refractory Metal · Zr 705C temper comparison
Zr 705C-ANN and Zr 705C-F are two conditions of the same refractory metal grade, Zr 705C: ANN (annealed) versus F (as fabricated). The chemistry is identical, so every difference below comes from the condition. Zr 705C-F is the stronger of the two: yield strength 386 MPa (56 ksi) against 355 MPa (51.5 ksi) for Zr 705C-ANN, about 9% more; tensile strength follows at 495 MPa (71.8 ksi) vs 470 MPa (68.2 ksi). In exchange, Zr 705C-ANN is the more ductile: elongation 17% versus 13% for Zr 705C-F, and Zr 705C-F is harder (190 HB vs 175 HB).

Zr 705C-ANN vs Zr 705C-F: 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.
