Nickel Alloy Alloy 59-CD vs Alloy 59 HF-A
Nickel Alloy · Alloy 59 temper comparison
Alloy 59-CD and Alloy 59 HF-A are two conditions of the same nickel alloy grade, Alloy 59: CD (cold drawn) versus HF-A (hot finished then solution annealed). The chemistry is identical, so every difference below comes from the condition. Alloy 59-CD is the stronger of the two: yield strength 750 MPa (109 ksi) against 340 MPa (49.3 ksi) for Alloy 59 HF-A, about 121% more; tensile strength follows at 950 MPa (138 ksi) vs 715 MPa (104 ksi). In exchange, Alloy 59 HF-A is the more ductile: elongation 50% versus 22% for Alloy 59-CD, and Alloy 59-CD is harder (290 HB vs 190 HB).
Alloy 59-CDChoose it when strength drives the design.
Alloy 59 HF-AChoose it when the part is bent, formed or impact-loaded.
Alloy 59-CD vs Alloy 59 HF-A: 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 59-CD vs Alloy 59 HF-A — frequently asked
Is Alloy 59-CD stronger than Alloy 59 HF-A?
Yes. Alloy 59-CD has a typical yield strength of 750 MPa (109 ksi) against 340 MPa (49.3 ksi) for Alloy 59 HF-A — about 121% more. Tensile strength is 950 MPa (138 ksi) vs 715 MPa (104 ksi).
Which condition does FabDigit quote by default, CD or HF-A?
SA is the default Alloy 59 condition in the FabDigit quote flow (neither CD nor HF-A). 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.
When should I choose Alloy 59-CD over Alloy 59 HF-A?
Pick Alloy 59-CD when strength drives the design. Pick Alloy 59 HF-A when the part is bent, formed or impact-loaded.
