Nickel Alloy N07776 CW+A-120 vs N07776-STA
Nickel Alloy · N07776 temper comparison
N07776 CW+A-120 and N07776-STA are two conditions of the same nickel alloy grade, N07776: CW+A-120 (CW+A 120 ksi) versus STA (solution treated and aged). The chemistry is identical, so every difference below comes from the condition. N07776-STA is the stronger of the two: yield strength 1,010 MPa (146 ksi) against 880 MPa (128 ksi) for N07776 CW+A-120, about 15% more; tensile strength follows at 1,300 MPa (189 ksi) vs 1,170 MPa (170 ksi). In exchange, N07776 CW+A-120 is the more ductile: elongation 25% versus 22% for N07776-STA, and N07776-STA is harder (340 HB vs 302 HB).
N07776 CW+A-120Choose it when the part is bent, formed or impact-loaded.
N07776-STAChoose it when strength drives the design.
N07776 CW+A-120 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.
