Nickel Alloy Alloy 333 vs Waspaloy
Nickel Alloy · grade comparison
Nickel Alloy Alloy 333 and Waspaloy are both nickel alloy grades. Waspaloy is the stronger of the two: yield strength 520 MPa (75.4 ksi) against 310 MPa (45 ksi) for Alloy 333, about 68% more; tensile strength follows at 930 MPa (135 ksi) vs 690 MPa (100 ksi). In exchange, Alloy 333 is the more ductile: elongation 50% versus 45% for Waspaloy, and Waspaloy is harder (250 HB vs 190 HB). Alloy 333 runs hotter in service (1,100°C vs 650°C continuous). On the shop floor, Alloy 333 welds better (very good vs fair) and Waspaloy sits in a lower cost tier (premium, $$$) than Alloy 333 (high, $$$$).
Alloy 333Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
WaspaloyChoose it when strength drives the design, or when cost is the deciding factor.
Alloy 333 vs Waspaloy: 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 vs Waspaloy — frequently asked
Is Waspaloy stronger than Alloy 333?
Yes. Waspaloy has a typical yield strength of 520 MPa (75.4 ksi) against 310 MPa (45 ksi) for Alloy 333 — about 68% more. Tensile strength is 930 MPa (135 ksi) vs 690 MPa (100 ksi).
Which is cheaper, Alloy 333 or Waspaloy?
Waspaloy is the lower-cost material: it sits in the premium tier ($$$) while Alloy 333 is high ($$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which is easier to machine, Alloy 333 or Waspaloy?
Alloy 333, by a small margin. Both rate poor for machinability — 25/100 against 18/100 for Waspaloy; for welding the order is Alloy 333 first (very good, 78/100) then Waspaloy (fair, 35/100).
