Nickel Alloy ENi-1 vs ERNiCrFe-11
Nickel Alloy · grade comparison
Nickel Alloy ENi-1 and ERNiCrFe-11 are both nickel alloy grades. ERNiCrFe-11 is the stronger of the two: yield strength 420 MPa (60.9 ksi) against 250 MPa (36.3 ksi) for ENi-1, about 68% more; tensile strength follows at 690 MPa (100 ksi) vs 440 MPa (63.8 ksi). ERNiCrFe-11 is the more ductile: elongation 40% versus 30% for ENi-1, and ERNiCrFe-11 is harder (200 HB vs 100 HB). ERNiCrFe-11 is lighter (8.19 g/cm³ vs 8.9 g/cm³ for ENi-1) and ERNiCrFe-11 is stiffer (211 GPa vs 200 GPa). On the shop floor, ENi-1 machines more easily (fair vs poor).
ENi-1Choose it when the part is machined in volume.
ERNiCrFe-11Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
ENi-1 vs ERNiCrFe-11: 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.

ENi-1 vs ERNiCrFe-11 — frequently asked
Is ERNiCrFe-11 stronger than ENi-1?
Yes. ERNiCrFe-11 has a typical yield strength of 420 MPa (60.9 ksi) against 250 MPa (36.3 ksi) for ENi-1 — about 68% more. Tensile strength is 690 MPa (100 ksi) vs 440 MPa (63.8 ksi).
Which is cheaper, ENi-1 or ERNiCrFe-11?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, ENi-1 or ERNiCrFe-11?
ENi-1. Its machinability rates fair (42/100) against poor (18/100) for ERNiCrFe-11.
