Nickel Alloy ENiCrCoMo-1 vs ERNiCrFe-5
Nickel Alloy · grade comparison
Nickel Alloy ENiCrCoMo-1 and ERNiCrFe-5 are both nickel alloy grades. ENiCrCoMo-1 is the stronger of the two: yield strength 430 MPa (62.4 ksi) against 400 MPa (58 ksi) for ERNiCrFe-5, about 8% more; tensile strength follows at 720 MPa (104 ksi) vs 655 MPa (95 ksi). ENiCrCoMo-1 is harder — 210 HB against 180 HB for ERNiCrFe-5 — which matters for wear surfaces and threads. ENiCrCoMo-1 runs hotter in service (1,100°C vs 980°C continuous) and ERNiCrFe-5 conducts electricity better (1.6 % IACS vs 1.4 % IACS). On the shop floor, ERNiCrFe-5 forms better (good vs fair).
ENiCrCoMo-1Choose it when strength drives the design, or when surface hardness matters.
ENiCrCoMo-1 vs ERNiCrFe-5: 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.

ENiCrCoMo-1 vs ERNiCrFe-5 — frequently asked
Is ENiCrCoMo-1 stronger than ERNiCrFe-5?
Yes. ENiCrCoMo-1 has a typical yield strength of 430 MPa (62.4 ksi) against 400 MPa (58 ksi) for ERNiCrFe-5 — about 8% more. Tensile strength is 720 MPa (104 ksi) vs 655 MPa (95 ksi).
Which is cheaper, ENiCrCoMo-1 or ERNiCrFe-5?
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 welds better, ENiCrCoMo-1 or ERNiCrFe-5?
ERNiCrFe-5. Its weldability rates excellent (92/100) against excellent (85/100) for ENiCrCoMo-1.
