Nickel Alloy Alloy 120-AW vs Alloy 120-CD

Nickel Alloy · Alloy 120 temper comparison

Alloy 120-AW and Alloy 120-CD are two conditions of the same nickel alloy grade, Alloy 120: AW (as-welded deposit) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. Alloy 120-CD is the stronger of the two: yield strength 620 MPa (89.9 ksi) against 390 MPa (56.6 ksi) for Alloy 120-AW, about 59% more; tensile strength follows at 900 MPa (131 ksi) vs 730 MPa (106 ksi). In exchange, Alloy 120-AW is the more ductile: elongation 35% versus 20% for Alloy 120-CD, and Alloy 120-CD is harder (250 HB vs 180 HB). Alloy 120-AW runs hotter in service (1,100°C vs 650°C continuous). On the shop floor, Alloy 120-AW welds better (very good vs good).

Alloy 120-AWChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.

Alloy 120-CDChoose it when strength drives the design.

Alloy 120-AW vs Alloy 120-CD — frequently asked

Is Alloy 120-CD stronger than Alloy 120-AW?

Yes. Alloy 120-CD has a typical yield strength of 620 MPa (89.9 ksi) against 390 MPa (56.6 ksi) for Alloy 120-AW — about 59% more. Tensile strength is 900 MPa (131 ksi) vs 730 MPa (106 ksi).

Which condition does FabDigit quote by default, AW or CD?

ANN is the default Alloy 120 condition in the FabDigit quote flow (neither AW nor CD). 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 is easier to machine, Alloy 120-AW or Alloy 120-CD?

Alloy 120-CD, by a small margin. Both rate poor for machinability — 28/100 against 20/100 for Alloy 120-AW; for welding the order is Alloy 120-AW first (very good, 75/100) then Alloy 120-CD (good, 65/100).
