Nickel Alloy FeNi vs Ni Briquette
Nickel Alloy · grade comparison
Nickel Alloy FeNi and Ni Briquette are both nickel alloy grades. FeNi is the stronger of the two: yield strength 340 MPa (49.3 ksi) against 150 MPa (21.8 ksi) for Ni Briquette, about 127% more; tensile strength follows at 470 MPa (68.2 ksi) vs 420 MPa (60.9 ksi). In exchange, Ni Briquette is the more ductile: elongation 45% versus 2.5% for FeNi, and FeNi is harder (260 HB vs 90 HB). FeNi is lighter (8 g/cm³ vs 8.9 g/cm³ for Ni Briquette) and FeNi runs hotter in service (550°C vs 315°C continuous). On the shop floor, Ni Briquette machines more easily (fair vs poor), Ni Briquette welds better (very good vs not recommended), and FeNi sits in a lower cost tier (standard, $$) than Ni Briquette (high, $$$$).
FeNiChoose it when strength drives the design, or when weight is the constraint.
Ni BriquetteChoose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
FeNi vs Ni Briquette: 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 Briquette — frequently asked
Is FeNi stronger than Ni Briquette?
Yes. FeNi has a typical yield strength of 340 MPa (49.3 ksi) against 150 MPa (21.8 ksi) for Ni Briquette — about 127% more. Tensile strength is 470 MPa (68.2 ksi) vs 420 MPa (60.9 ksi).
Which is cheaper, FeNi or Ni Briquette?
FeNi is the lower-cost material: it sits in the standard tier ($$) while Ni Briquette is high ($$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which is easier to machine, FeNi or Ni Briquette?
Ni Briquette. Its machinability rates fair (42/100) against poor (22/100) for FeNi; for welding the order is Ni Briquette first (very good, 75/100) then FeNi (not recommended, 14/100).
