Nickel Alloy N07776 CW+A-150 vs N07776-STA
Nickel Alloy · N07776 temper comparison
N07776 CW+A-150 and N07776-STA are two conditions of the same nickel alloy grade, N07776: CW+A-150 (CW+A 150 ksi) versus STA (solution treated and aged). The chemistry is identical, so every difference below comes from the condition. N07776 CW+A-150 is the stronger of the two: yield strength 1,090 MPa (158 ksi) against 1,010 MPa (146 ksi) for N07776-STA, about 8% more. In exchange, N07776-STA is the more ductile: elongation 22% versus 17% for N07776 CW+A-150, and N07776 CW+A-150 is harder (363 HB vs 340 HB).

N07776 CW+A-150 vs N07776-STA: 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.
