Nickel Alloy ENiCrCoMo-1 vs ERNiCrMo-2
Nickel Alloy · grade comparison
Nickel Alloy ENiCrCoMo-1 and ERNiCrMo-2 are both nickel alloy grades. Both yield at about 430 MPa — strength does not separate them. ENiCrCoMo-1 is harder — 17 HRC against 13 HRC for ERNiCrMo-2 — which matters for wear surfaces and threads. ENiCrCoMo-1 conducts heat better (13.6 W/m·K vs 9.1 W/m·K). On the shop floor, ERNiCrMo-2 forms better (good vs fair).

ENiCrCoMo-1 vs ERNiCrMo-2: 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 ERNiCrMo-2 — frequently asked
What is the difference between ENiCrCoMo-1 and ERNiCrMo-2?
Nickel Alloy ENiCrCoMo-1 and ERNiCrMo-2 are both nickel alloy grades. Both yield at about 430 MPa — strength does not separate them. ENiCrCoMo-1 is harder — 17 HRC against 13 HRC for ERNiCrMo-2 — which matters for wear surfaces and threads.
Which is cheaper, ENiCrCoMo-1 or ERNiCrMo-2?
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, ENiCrCoMo-1 or ERNiCrMo-2?
ERNiCrMo-2, by a small margin. Both rate poor for machinability — 25/100 against 20/100 for ENiCrCoMo-1.
