Nickel Alloy CZ-100-ANN vs CZ-100-SR
Nickel Alloy · CZ-100 temper comparison
CZ-100-ANN and CZ-100-SR are two conditions of the same nickel alloy grade, CZ-100: ANN (annealed) versus SR (stress relieved). The chemistry is identical, so every difference below comes from the condition. CZ-100-SR is the stronger of the two: yield strength 150 MPa (21.8 ksi) against 140 MPa (20.3 ksi) for CZ-100-ANN, about 7% more. In exchange, CZ-100-ANN is the more ductile: elongation 32% versus 28% for CZ-100-SR, and CZ-100-SR is harder (105 HB vs 95 HB).
CZ-100-ANNChoose it when the part is bent, formed or impact-loaded.
CZ-100-SRChoose it when strength drives the design.
CZ-100-ANN vs CZ-100-SR: 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.

CZ-100-ANN vs CZ-100-SR — frequently asked
Is CZ-100-SR stronger than CZ-100-ANN?
Yes. CZ-100-SR has a typical yield strength of 150 MPa (21.8 ksi) against 140 MPa (20.3 ksi) for CZ-100-ANN — about 7% more. Tensile strength is 370 MPa (53.7 ksi) vs 360 MPa (52.2 ksi).
Which condition does FabDigit quote by default, ANN or SR?
F is the default CZ-100 condition in the FabDigit quote flow (neither ANN nor SR). 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 CZ-100-ANN over CZ-100-SR?
Pick CZ-100-ANN when the part is bent, formed or impact-loaded. Pick CZ-100-SR when strength drives the design.
