Nickel Alloy FeNi vs Ni Shot
Nickel Alloy · grade comparison
Nickel Alloy FeNi and Ni Shot are both nickel alloy grades. FeNi is the stronger of the two: yield strength 340 MPa (49.3 ksi) against 120 MPa (17.4 ksi) for Ni Shot, about 183% more; tensile strength follows at 470 MPa (68.2 ksi) vs 420 MPa (60.9 ksi). In exchange, Ni Shot is the more ductile: elongation 45% versus 2.5% for FeNi, and FeNi is harder (260 HB vs 95 HB). FeNi is lighter (8 g/cm³ vs 8.9 g/cm³ for Ni Shot) and Ni Shot conducts heat better (88 W/m·K vs 16 W/m·K). On the shop floor, FeNi sits in a lower cost tier (standard, $$) than Ni Shot (high, $$$$).
FeNiChoose it when strength drives the design, or when weight is the constraint.
Ni ShotChoose it when the part is bent, formed or impact-loaded.
FeNi 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.

FeNi vs Ni Shot — frequently asked
Is FeNi stronger than Ni Shot?
Yes. FeNi has a typical yield strength of 340 MPa (49.3 ksi) against 120 MPa (17.4 ksi) for Ni Shot — about 183% more. Tensile strength is 470 MPa (68.2 ksi) vs 420 MPa (60.9 ksi).
Which is cheaper, FeNi or Ni Shot?
FeNi is the lower-cost material: it sits in the standard tier ($$) while Ni Shot is high ($$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
When should I choose FeNi over Ni Shot?
Pick FeNi when strength drives the design, or when weight is the constraint. Pick Ni Shot when the part is bent, formed or impact-loaded.
Ready to make it?
Upload a CAD file and FabDigit prices the part in FeNi and Ni Shot side by side — material, machining time, tolerance and finish in one quote. Certified material data ships with the order on request.
