Copper Alloy CC484K-GC vs CC484K-GS
Copper Alloy · CC484K temper comparison
CC484K-GC and CC484K-GS are two conditions of the same copper alloy grade, CC484K: GC (continuously cast bar / tube) versus GS (sand cast). The chemistry is identical, so every difference below comes from the condition. CC484K-GC is the stronger of the two: yield strength 205 MPa (29.7 ksi) against 175 MPa (25.4 ksi) for CC484K-GS, about 17% more; tensile strength follows at 340 MPa (49.3 ksi) vs 300 MPa (43.5 ksi). CC484K-GC is harder — 110 HB against 95 HB for CC484K-GS — which matters for wear surfaces and threads. CC484K-GC is stiffer (108 GPa vs 100 GPa).
CC484K-GCChoose it when strength drives the design, or when surface hardness matters.
CC484K-GC vs CC484K-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.

CC484K-GC vs CC484K-GS — frequently asked
Is CC484K-GC stronger than CC484K-GS?
Yes. CC484K-GC has a typical yield strength of 205 MPa (29.7 ksi) against 175 MPa (25.4 ksi) for CC484K-GS — about 17% more. Tensile strength is 340 MPa (49.3 ksi) vs 300 MPa (43.5 ksi).
Which condition does FabDigit quote by default, GC or GS?
GZ is the default CC484K condition in the FabDigit quote flow (neither GC nor GS). 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, CC484K-GC or CC484K-GS?
CC484K-GC, by a small margin. Both rate fair for machinability — 50/100 against 45/100 for CC484K-GS.
