Nickel Alloy BNi-1 vs ENiCrMo-13
Nickel Alloy · grade comparison
Nickel Alloy BNi-1 and ENiCrMo-13 are both nickel alloy grades. ENiCrMo-13 is the stronger of the two: tensile strength 745 MPa (108 ksi) against 550 MPa (79.8 ksi) for BNi-1, about 35% more. ENiCrMo-13 is the more ductile: elongation 40% versus 1% for BNi-1, and BNi-1 is harder (520 HB vs 200 HB). BNi-1 is lighter (7.89 g/cm³ vs 8.6 g/cm³ for ENiCrMo-13) and BNi-1 runs hotter in service (900°C vs 450°C continuous). On the shop floor, ENiCrMo-13 machines more easily (poor vs not recommended) and ENiCrMo-13 welds better (excellent vs not recommended).
BNi-1Choose it when weight is the constraint, or when the part sees heat.
ENiCrMo-13Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
BNi-1 vs ENiCrMo-13: 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.

BNi-1 vs ENiCrMo-13 — frequently asked
Is ENiCrMo-13 stronger than BNi-1?
Yes. ENiCrMo-13 has a typical tensile strength of 745 MPa (108 ksi) against 550 MPa (79.8 ksi) for BNi-1 — about 35% more.
Which is cheaper, BNi-1 or ENiCrMo-13?
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, BNi-1 or ENiCrMo-13?
ENiCrMo-13. Its machinability rates poor (20/100) against not recommended (6/100) for BNi-1; for welding the order is ENiCrMo-13 first (excellent, 85/100) then BNi-1 (not recommended, 10/100).
