Nickel Alloy N07773-CD vs N07773-SA
Nickel Alloy · N07773 temper comparison
N07773-CD and N07773-SA are two conditions of the same nickel alloy grade, N07773: CD (cold drawn) versus SA (solution annealed). The chemistry is identical, so every difference below comes from the condition. N07773-CD is the stronger of the two: yield strength 1,100 MPa (160 ksi) against 450 MPa (65.3 ksi) for N07773-SA, about 144% more; tensile strength follows at 1,300 MPa (189 ksi) vs 900 MPa (131 ksi). In exchange, N07773-SA is the more ductile: elongation 45% versus 12% for N07773-CD, and N07773-CD is harder (375 HB vs 200 HB). On the shop floor, N07773-SA welds better (good vs fair).
N07773-CDChoose it when strength drives the design.
N07773-SAChoose it when the part is bent, formed or impact-loaded, or when it will be welded.
N07773-CD vs N07773-SA: 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.

N07773-CD vs N07773-SA — frequently asked
Is N07773-CD stronger than N07773-SA?
Yes. N07773-CD has a typical yield strength of 1,100 MPa (160 ksi) against 450 MPa (65.3 ksi) for N07773-SA — about 144% more. Tensile strength is 1,300 MPa (189 ksi) vs 900 MPa (131 ksi).
Which condition does FabDigit quote by default, CD or SA?
STA is the default N07773 condition in the FabDigit quote flow (neither CD nor SA). 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, N07773-CD or N07773-SA?
N07773-SA, by a small margin. Both rate poor for machinability — 22/100 against 16/100 for N07773-CD; for welding the order is N07773-SA first (good, 60/100) then N07773-CD (fair, 35/100).
