Nickel Alloy Waspaloy CD+A vs Waspaloy Solution Annealed
Nickel Alloy · Waspaloy temper comparison
Waspaloy CD+A and Waspaloy Solution Annealed are two conditions of the same nickel alloy grade, Waspaloy: CD+A (cold drawn bar/wire, then precipitation aged) versus Solution Annealed. The chemistry is identical, so every difference below comes from the condition. Waspaloy CD+A is the stronger of the two: yield strength 1,000 MPa (145 ksi) against 520 MPa (75.4 ksi) for Waspaloy Solution Annealed, about 92% more; tensile strength follows at 1,420 MPa (206 ksi) vs 930 MPa (135 ksi). In exchange, Waspaloy Solution Annealed is the more ductile: elongation 45% versus 16% for Waspaloy CD+A, and Waspaloy CD+A is harder (375 HB vs 250 HB).

Waspaloy CD+A vs Waspaloy Solution Annealed: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all nickel alloy 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.
