Nickel Alloy CY5SnBiM-F vs CY5SnBiM-SR
Nickel Alloy · CY5SnBiM temper comparison
CY5SnBiM-F and CY5SnBiM-SR are two conditions of the same nickel alloy grade, CY5SnBiM: F (as fabricated) versus SR (stress relieved). The chemistry is identical, so every difference below comes from the condition. CY5SnBiM-F is the stronger of the two: yield strength 200 MPa (29 ksi) against 185 MPa (26.8 ksi) for CY5SnBiM-SR, about 8% more; tensile strength follows at 390 MPa (56.6 ksi) vs 370 MPa (53.7 ksi). In exchange, CY5SnBiM-SR is the more ductile: elongation 22% versus 18% for CY5SnBiM-F, and CY5SnBiM-F is harder (130 HB vs 120 HB).
CY5SnBiM-FChoose it when strength drives the design.
CY5SnBiM-SRChoose it when the part is bent, formed or impact-loaded.
CY5SnBiM-F vs CY5SnBiM-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.

CY5SnBiM-F vs CY5SnBiM-SR — frequently asked
Is CY5SnBiM-F stronger than CY5SnBiM-SR?
Yes. CY5SnBiM-F has a typical yield strength of 200 MPa (29 ksi) against 185 MPa (26.8 ksi) for CY5SnBiM-SR — about 8% more. Tensile strength is 390 MPa (56.6 ksi) vs 370 MPa (53.7 ksi).
Which condition does FabDigit quote by default, F or SR?
F is the default CY5SnBiM condition in the FabDigit quote flow. 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 CY5SnBiM-F over CY5SnBiM-SR?
Pick CY5SnBiM-F when strength drives the design. Pick CY5SnBiM-SR when the part is bent, formed or impact-loaded.
