Nickel Alloy Nimonic 86-CD vs Nimonic 86-HF
Nickel Alloy · Nimonic 86 temper comparison
Nimonic 86-CD and Nimonic 86-HF are two conditions of the same nickel alloy grade, Nimonic 86: CD (cold drawn) versus HF (hot Finished / Hot Rolled). The chemistry is identical, so every difference below comes from the condition. Nimonic 86-CD is the stronger of the two: yield strength 700 MPa (102 ksi) against 450 MPa (65.3 ksi) for Nimonic 86-HF, about 56% more; tensile strength follows at 950 MPa (138 ksi) vs 850 MPa (123 ksi). In exchange, Nimonic 86-HF is the more ductile: elongation 40% versus 25% for Nimonic 86-CD, and Nimonic 86-CD is harder (260 HB vs 215 HB). Nimonic 86-HF runs hotter in service (1,100°C vs 600°C continuous).
Nimonic 86-CDChoose it when strength drives the design.
Nimonic 86-HFChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
Nimonic 86-CD vs Nimonic 86-HF: 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.

Nimonic 86-CD vs Nimonic 86-HF — frequently asked
Is Nimonic 86-CD stronger than Nimonic 86-HF?
Yes. Nimonic 86-CD has a typical yield strength of 700 MPa (102 ksi) against 450 MPa (65.3 ksi) for Nimonic 86-HF — about 56% more. Tensile strength is 950 MPa (138 ksi) vs 850 MPa (123 ksi).
Which condition does FabDigit quote by default, CD or HF?
SA is the default Nimonic 86 condition in the FabDigit quote flow (neither CD nor HF). 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, Nimonic 86-CD or Nimonic 86-HF?
Nimonic 86-CD, by a small margin. Both rate poor for machinability — 26/100 against 20/100 for Nimonic 86-HF; for welding the order is Nimonic 86-HF first (very good, 72/100) then Nimonic 86-CD (good, 65/100).
