Nickel Alloy BNi-10 vs ENi-1
Nickel Alloy · grade comparison
Nickel Alloy BNi-10 and ENi-1 are both nickel alloy grades. BNi-10 is the stronger of the two: tensile strength 550 MPa (79.8 ksi) against 440 MPa (63.8 ksi) for ENi-1, about 25% more. In exchange, ENi-1 is the more ductile: elongation 30% versus 1% for BNi-10, and BNi-10 is harder (520 HV vs 105 HV). BNi-10 runs hotter in service (980°C vs 400°C continuous) and ENi-1 conducts heat better (42 W/m·K vs 20 W/m·K). On the shop floor, ENi-1 machines more easily (fair vs not recommended) and ENi-1 welds better (excellent vs not recommended).
BNi-10Choose it when strength drives the design, or when the part sees heat.
ENi-1Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
BNi-10 vs ENi-1: 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-10 vs ENi-1 — frequently asked
Is BNi-10 stronger than ENi-1?
Yes. BNi-10 has a typical tensile strength of 550 MPa (79.8 ksi) against 440 MPa (63.8 ksi) for ENi-1 — about 25% more.
Which is cheaper, BNi-10 or ENi-1?
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-10 or ENi-1?
ENi-1. Its machinability rates fair (42/100) against not recommended (5/100) for BNi-10; for welding the order is ENi-1 first (excellent, 85/100) then BNi-10 (not recommended, 10/100).
