Nickel Alloy Inconel 600 vs NiCr26MoW
Nickel Alloy · grade comparison
Nickel Alloy Inconel 600 and NiCr26MoW are both nickel alloy grades. NiCr26MoW is the stronger of the two: yield strength 350 MPa (50.8 ksi) against 255 MPa (37 ksi) for Inconel 600, about 37% more; tensile strength follows at 730 MPa (106 ksi) vs 620 MPa (89.9 ksi). NiCr26MoW is harder — 180 HB against 150 HB for Inconel 600 — which matters for wear surfaces and threads. Inconel 600 conducts heat better (14.9 W/m·K vs 10.5 W/m·K). On the shop floor, Inconel 600 welds better (80 vs 70 out of 100) and Inconel 600 forms better (very good vs good).

NiCr26MoWChoose it when strength drives the design, or when surface hardness matters.
Inconel 600 vs NiCr26MoW: 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.

Inconel 600 vs NiCr26MoW — frequently asked
Is NiCr26MoW stronger than Inconel 600?
Yes. NiCr26MoW has a typical yield strength of 350 MPa (50.8 ksi) against 255 MPa (37 ksi) for Inconel 600 — about 37% more. Tensile strength is 730 MPa (106 ksi) vs 620 MPa (89.9 ksi).
Which is cheaper, Inconel 600 or NiCr26MoW?
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, Inconel 600 or NiCr26MoW?
Inconel 600, by a small margin. Both rate poor for machinability — 28/100 against 22/100 for NiCr26MoW; for welding the order is Inconel 600 first (very good, 80/100) then NiCr26MoW (very good, 70/100).
