Copper Alloy CC480K-GC vs CC480K-GS
Copper Alloy · CC480K temper comparison
CC480K-GC and CC480K-GS are two conditions of the same copper alloy grade, CC480K: GC (continuous cast bar / tube) versus GS (sand cast). The chemistry is identical, so every difference below comes from the condition. CC480K-GC is the stronger of the two: yield strength 190 MPa (27.6 ksi) against 150 MPa (21.8 ksi) for CC480K-GS, about 27% more; tensile strength follows at 330 MPa (47.9 ksi) vs 290 MPa (42.1 ksi). In exchange, CC480K-GS is the more ductile: elongation 10% versus 8% for CC480K-GC, and CC480K-GC is harder (95 HB vs 85 HB).
CC480K-GCChoose it when strength drives the design.
CC480K-GSChoose it when the part is bent, formed or impact-loaded.
CC480K-GC vs CC480K-GS: 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.

CC480K-GC vs CC480K-GS — frequently asked
Is CC480K-GC stronger than CC480K-GS?
Yes. CC480K-GC has a typical yield strength of 190 MPa (27.6 ksi) against 150 MPa (21.8 ksi) for CC480K-GS — about 27% more. Tensile strength is 330 MPa (47.9 ksi) vs 290 MPa (42.1 ksi).
Which condition does FabDigit quote by default, GC or GS?
GC is the default CC480K 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.
Which is easier to machine, CC480K-GC or CC480K-GS?
CC480K-GC, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for CC480K-GS.
