Nickel Alloy NiCr26MoW-AW vs NiCr26MoW-CW
Nickel Alloy · NiCr26MoW temper comparison
NiCr26MoW-AW and NiCr26MoW-CW are two conditions of the same nickel alloy grade, NiCr26MoW: AW (as-welded deposit) versus CW (cold worked). The chemistry is identical, so every difference below comes from the condition. NiCr26MoW-CW is the stronger of the two: yield strength 800 MPa (116 ksi) against 400 MPa (58 ksi) for NiCr26MoW-AW, about 100% more; tensile strength follows at 1,000 MPa (145 ksi) vs 700 MPa (102 ksi). In exchange, NiCr26MoW-AW is the more ductile: elongation 32% versus 12% for NiCr26MoW-CW, and NiCr26MoW-CW is harder (290 HB vs 200 HB). NiCr26MoW-AW runs hotter in service (1,100°C vs 600°C continuous).
NiCr26MoW-AWChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
NiCr26MoW-CWChoose it when strength drives the design.
NiCr26MoW-AW vs NiCr26MoW-CW: 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.

NiCr26MoW-AW vs NiCr26MoW-CW — frequently asked
Is NiCr26MoW-CW stronger than NiCr26MoW-AW?
Yes. NiCr26MoW-CW has a typical yield strength of 800 MPa (116 ksi) against 400 MPa (58 ksi) for NiCr26MoW-AW — about 100% more. Tensile strength is 1,000 MPa (145 ksi) vs 700 MPa (102 ksi).
Which condition does FabDigit quote by default, AW or CW?
SA is the default NiCr26MoW condition in the FabDigit quote flow (neither AW nor CW). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which welds better, NiCr26MoW-AW or NiCr26MoW-CW?
NiCr26MoW-AW. Its weldability rates good (65/100) against good (60/100) for NiCr26MoW-CW.
