Copper Alloy CC497K-GS vs CC497K-GZ
Copper Alloy · CC497K temper comparison
CC497K-GS and CC497K-GZ are two conditions of the same copper alloy grade, CC497K: GS (sand cast) versus GZ (centrifugally cast). The chemistry is identical, so every difference below comes from the condition. CC497K-GZ is the stronger of the two: yield strength 85 MPa (12.3 ksi) against 70 MPa (10.2 ksi) for CC497K-GS, about 21% more; tensile strength follows at 190 MPa (27.6 ksi) vs 165 MPa (23.9 ksi). CC497K-GZ is harder — 52 HB against 47 HB for CC497K-GS — which matters for wear surfaces and threads. CC497K-GZ is stiffer (72 GPa vs 68 GPa).
CC497K-GZChoose it when strength drives the design, or when surface hardness matters.
CC497K-GS vs CC497K-GZ: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all copper 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.

CC497K-GS vs CC497K-GZ — frequently asked
Is CC497K-GZ stronger than CC497K-GS?
Yes. CC497K-GZ has a typical yield strength of 85 MPa (12.3 ksi) against 70 MPa (10.2 ksi) for CC497K-GS — about 21% more. Tensile strength is 190 MPa (27.6 ksi) vs 165 MPa (23.9 ksi).
Which condition does FabDigit quote by default, GS or GZ?
GC is the default CC497K condition in the FabDigit quote flow (neither GS nor GZ). 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 CC497K-GS over CC497K-GZ?
Pick CC497K-GZ when strength drives the design, or when surface hardness matters.
