Nickel Alloy Alloy 22 vs N10624
Nickel Alloy · grade comparison
Nickel Alloy Alloy 22 and N10624 are both nickel alloy grades. N10624 is the stronger of the two: tensile strength 890 MPa (129 ksi) against 800 MPa (116 ksi) for Alloy 22, about 11% more. In exchange, Alloy 22 is the more ductile: elongation 62% versus 55% for N10624, and N10624 is harder (95 HRB vs 88 HRB). Alloy 22 is lighter (8.69 g/cm³ vs 9.22 g/cm³ for N10624) and Alloy 22 runs hotter in service (675°C vs 480°C continuous). On the shop floor, Alloy 22 welds better (excellent vs good).
Alloy 22Choose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
N10624Choose it when strength drives the design.
Alloy 22 vs N10624: 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 N10624 — frequently asked
Is N10624 stronger than Alloy 22?
Yes. N10624 has a typical tensile strength of 890 MPa (129 ksi) against 800 MPa (116 ksi) for Alloy 22 — about 11% more.
Which is cheaper, Alloy 22 or N10624?
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 N10624?
N10624, by a small margin. Both rate poor for machinability — 20/100 against 15/100 for Alloy 22; for welding the order is Alloy 22 first (excellent, 85/100) then N10624 (good, 65/100).
