Copper Alloy CC482K-GS vs CC482K-GZ
Copper Alloy · CC482K temper comparison
CC482K-GS and CC482K-GZ are two conditions of the same copper alloy grade, CC482K: GS (sand cast) versus GZ (centrifugal cast). The chemistry is identical, so every difference below comes from the condition. CC482K-GZ is the stronger of the two: yield strength 185 MPa (26.8 ksi) against 150 MPa (21.8 ksi) for CC482K-GS, about 23% more; tensile strength follows at 320 MPa (46.4 ksi) vs 270 MPa (39.2 ksi). In exchange, CC482K-GS is the more ductile: elongation 8% versus 7% for CC482K-GZ, and CC482K-GZ is harder (100 HB vs 85 HB). CC482K-GZ is stiffer (105 GPa vs 98 GPa).
CC482K-GSChoose it when the part is bent, formed or impact-loaded.
CC482K-GZChoose it when strength drives the design.
CC482K-GS vs CC482K-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.

CC482K-GS vs CC482K-GZ — frequently asked
Is CC482K-GZ stronger than CC482K-GS?
Yes. CC482K-GZ has a typical yield strength of 185 MPa (26.8 ksi) against 150 MPa (21.8 ksi) for CC482K-GS — about 23% more. Tensile strength is 320 MPa (46.4 ksi) vs 270 MPa (39.2 ksi).
Which condition does FabDigit quote by default, GS or GZ?
GC is the default CC482K 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 CC482K-GS over CC482K-GZ?
Pick CC482K-GS when the part is bent, formed or impact-loaded. Pick CC482K-GZ when strength drives the design.
