Nickel Alloy GX50NiCrCoW35-25-15-5-AC vs GX50NiCrCoW35-25-15-5-SR
Nickel Alloy · GX50NiCrCoW35-25-15-5 temper comparison
GX50NiCrCoW35-25-15-5-AC and GX50NiCrCoW35-25-15-5-SR are two conditions of the same nickel alloy grade, GX50NiCrCoW35-25-15-5: AC (spheroidize annealed) versus SR (stress relieved). The chemistry is identical, so every difference below comes from the condition. GX50NiCrCoW35-25-15-5-AC is the stronger of the two: yield strength 290 MPa (42.1 ksi) against 270 MPa (39.2 ksi) for GX50NiCrCoW35-25-15-5-SR, about 7% more. In exchange, GX50NiCrCoW35-25-15-5-SR is the more ductile: elongation 8% versus 5% for GX50NiCrCoW35-25-15-5-AC.

GX50NiCrCoW35-25-15-5-SRChoose it when the part is bent, formed or impact-loaded.
GX50NiCrCoW35-25-15-5-AC vs GX50NiCrCoW35-25-15-5-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.
