Nickel Alloy BNi-11 vs ENiCrCoMo-1
Nickel Alloy · grade comparison
Nickel Alloy BNi-11 and ENiCrCoMo-1 are both nickel alloy grades. BNi-11 is harder — 52 HRC against 17 HRC for ENiCrCoMo-1 — which matters for wear surfaces and threads. ENiCrCoMo-1 is lighter (8.36 g/cm³ vs 8.7 g/cm³ for BNi-11) and ENiCrCoMo-1 is stiffer (211 GPa vs 200 GPa). On the shop floor, ENiCrCoMo-1 machines more easily (poor vs not recommended) and ENiCrCoMo-1 welds better (excellent vs not recommended).
BNi-11Choose it when surface hardness matters.
ENiCrCoMo-1Choose it when weight is the constraint, or when the part sees heat.
BNi-11 vs ENiCrCoMo-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-11 vs ENiCrCoMo-1 — frequently asked
What is the difference between BNi-11 and ENiCrCoMo-1?
Nickel Alloy BNi-11 and ENiCrCoMo-1 are both nickel alloy grades. BNi-11 is harder — 52 HRC against 17 HRC for ENiCrCoMo-1 — which matters for wear surfaces and threads. ENiCrCoMo-1 is lighter (8.36 g/cm³ vs 8.7 g/cm³ for BNi-11) and ENiCrCoMo-1 is stiffer (211 GPa vs 200 GPa).
Which is cheaper, BNi-11 or ENiCrCoMo-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-11 or ENiCrCoMo-1?
ENiCrCoMo-1. Its machinability rates poor (20/100) against not recommended (5/100) for BNi-11; for welding the order is ENiCrCoMo-1 first (excellent, 85/100) then BNi-11 (not recommended, 10/100).
