Nickel Alloy ENiCrCoMo-1 vs ENiMo-7
Nickel Alloy · grade comparison
Nickel Alloy ENiCrCoMo-1 and ENiMo-7 are both nickel alloy grades. ENiMo-7 is the stronger of the two: yield strength 470 MPa (68.2 ksi) against 430 MPa (62.4 ksi) for ENiCrCoMo-1, about 9% more; tensile strength follows at 820 MPa (119 ksi) vs 720 MPa (104 ksi). In exchange, ENiCrCoMo-1 is the more ductile: elongation 38% versus 33% for ENiMo-7, and ENiMo-7 is harder (230 HB vs 210 HB). ENiCrCoMo-1 is lighter (8.36 g/cm³ vs 9.22 g/cm³ for ENiMo-7) and ENiCrCoMo-1 runs hotter in service (1,100°C vs 425°C continuous). On the shop floor, ENiCrCoMo-1 welds better (excellent vs very good).
ENiCrCoMo-1Choose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
ENiMo-7Choose it when strength drives the design.
ENiCrCoMo-1 vs ENiMo-7: 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 ENiMo-7 — frequently asked
Is ENiMo-7 stronger than ENiCrCoMo-1?
Yes. ENiMo-7 has a typical yield strength of 470 MPa (68.2 ksi) against 430 MPa (62.4 ksi) for ENiCrCoMo-1 — about 9% more. Tensile strength is 820 MPa (119 ksi) vs 720 MPa (104 ksi).
Which is cheaper, ENiCrCoMo-1 or ENiMo-7?
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 ENiMo-7?
ENiCrCoMo-1. Its weldability rates excellent (85/100) against very good (70/100) for ENiMo-7.
