Nickel Alloy Inconel 718 vs Ni Shot
Nickel Alloy · grade comparison
Nickel Alloy Inconel 718 and Ni Shot are both nickel alloy grades. Inconel 718 is the stronger of the two: yield strength 550 MPa (79.8 ksi) against 120 MPa (17.4 ksi) for Ni Shot, about 4.6 times as much; tensile strength follows at 965 MPa (140 ksi) vs 420 MPa (60.9 ksi). Inconel 718 is harder — 200 HB against 95 HB for Ni Shot — which matters for wear surfaces and threads. Inconel 718 is lighter (8.19 g/cm³ vs 8.9 g/cm³ for Ni Shot) and Ni Shot conducts heat better (88 W/m·K vs 11.4 W/m·K). On the shop floor, Inconel 718 sits in a lower cost tier (premium, $$$) than Ni Shot (high, $$$$).
Inconel 718Choose it when strength drives the design, or when surface hardness matters.
Inconel 718 vs Ni Shot: 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.
