Nickel Alloy Alloy 22 vs N06255
Nickel Alloy · grade comparison
Nickel Alloy Alloy 22 and N06255 are both nickel alloy grades. Alloy 22 is the stronger of the two: yield strength 400 MPa (58 ksi) against 355 MPa (51.5 ksi) for N06255, about 13% more; tensile strength follows at 800 MPa (116 ksi) vs 760 MPa (110 ksi). Alloy 22 is the more ductile: elongation 62% versus 55% for N06255.
Alloy 22Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
Alloy 22 vs N06255: 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.

Alloy 22 vs N06255 — frequently asked
Is Alloy 22 stronger than N06255?
Yes. Alloy 22 has a typical yield strength of 400 MPa (58 ksi) against 355 MPa (51.5 ksi) for N06255 — about 13% more. Tensile strength is 800 MPa (116 ksi) vs 760 MPa (110 ksi).
Which is cheaper, Alloy 22 or N06255?
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, Alloy 22 or N06255?
N06255, by a small margin. Both rate poor for machinability — 20/100 against 15/100 for Alloy 22.
