Nickel Alloy Alloy 333-AW vs Alloy 333-CW
Nickel Alloy · Alloy 333 temper comparison
Alloy 333-AW and Alloy 333-CW are two conditions of the same nickel alloy grade, Alloy 333: AW (as-welded deposit) versus CW (cold worked). The chemistry is identical, so every difference below comes from the condition. Alloy 333-CW is the stronger of the two: yield strength 700 MPa (102 ksi) against 380 MPa (55.1 ksi) for Alloy 333-AW, about 84% more; tensile strength follows at 950 MPa (138 ksi) vs 680 MPa (98.6 ksi). In exchange, Alloy 333-AW is the more ductile: elongation 35% versus 15% for Alloy 333-CW, and Alloy 333-CW is harder (255 HB vs 205 HB). Alloy 333-AW runs hotter in service (1,050°C vs 650°C continuous). On the shop floor, Alloy 333-AW welds better (very good vs good).
Alloy 333-AWChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Alloy 333-CWChoose it when strength drives the design.
Alloy 333-AW vs Alloy 333-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.

Alloy 333-AW vs Alloy 333-CW — frequently asked
Is Alloy 333-CW stronger than Alloy 333-AW?
Yes. Alloy 333-CW has a typical yield strength of 700 MPa (102 ksi) against 380 MPa (55.1 ksi) for Alloy 333-AW — about 84% more. Tensile strength is 950 MPa (138 ksi) vs 680 MPa (98.6 ksi).
Which condition does FabDigit quote by default, AW or CW?
SA is the default Alloy 333 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, Alloy 333-AW or Alloy 333-CW?
Alloy 333-AW. Its weldability rates very good (78/100) against good (68/100) for Alloy 333-CW.
