Nickel Alloy Inconel 718 vs N07773
Nickel Alloy · grade comparison
Nickel Alloy Inconel 718 and N07773 are both nickel alloy grades. N07773 is the stronger of the two: yield strength 1,030 MPa (149 ksi) against 550 MPa (79.8 ksi) for Inconel 718, about 87% more; tensile strength follows at 1,275 MPa (185 ksi) vs 965 MPa (140 ksi). In exchange, Inconel 718 is the more ductile: elongation 45% versus 16% for N07773, and N07773 is harder (350 HB vs 200 HB). N07773 runs hotter in service (650°C vs 540°C continuous). On the shop floor, Inconel 718 welds better (very good vs fair) and Inconel 718 sits in a lower cost tier (premium, $$$) than N07773 (high, $$$$).
Inconel 718Choose it when the part is bent, formed or impact-loaded, or when it will be welded.
N07773Choose it when strength drives the design, or when the part sees heat.
Inconel 718 vs N07773: 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.
