Nickel Alloy N07776 vs Waspaloy
Nickel Alloy · grade comparison
Nickel Alloy N07776 and Waspaloy are both nickel alloy grades. N07776 is the stronger of the two: yield strength 1,010 MPa (146 ksi) against 520 MPa (75.4 ksi) for Waspaloy, about 94% more; tensile strength follows at 1,300 MPa (189 ksi) vs 930 MPa (135 ksi). In exchange, Waspaloy is the more ductile: elongation 45% versus 22% for N07776, and N07776 is harder (340 HB vs 250 HB). On the shop floor, Waspaloy sits in a lower cost tier (premium, $$$) than N07776 (high, $$$$).
N07776Choose it when strength drives the design.
WaspaloyChoose it when the part is bent, formed or impact-loaded, or when cost is the deciding factor.
N07776 vs Waspaloy: 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.
