Copper Alloy CC496K-GC vs CC496K-GS
Copper Alloy · CC496K temper comparison
CC496K-GC and CC496K-GS are two conditions of the same copper alloy grade, CC496K: GC (continuously cast bar / tube) versus GS (sand cast). The chemistry is identical, so every difference below comes from the condition. CC496K-GC is the stronger of the two: yield strength 110 MPa (16 ksi) against 90 MPa (13.1 ksi) for CC496K-GS, about 22% more; tensile strength follows at 220 MPa (31.9 ksi) vs 190 MPa (27.6 ksi). In exchange, CC496K-GS is the more ductile: elongation 10% versus 9% for CC496K-GC, and CC496K-GC is harder (68 HB vs 60 HB). CC496K-GC is stiffer (78 GPa vs 74 GPa).
CC496K-GCChoose it when strength drives the design.
CC496K-GSChoose it when the part is bent, formed or impact-loaded.
CC496K-GC vs CC496K-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.

CC496K-GC vs CC496K-GS — frequently asked
Is CC496K-GC stronger than CC496K-GS?
Yes. CC496K-GC has a typical yield strength of 110 MPa (16 ksi) against 90 MPa (13.1 ksi) for CC496K-GS — about 22% more. Tensile strength is 220 MPa (31.9 ksi) vs 190 MPa (27.6 ksi).
Which condition does FabDigit quote by default, GC or GS?
GC is the default CC496K 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.
When should I choose CC496K-GC over CC496K-GS?
Pick CC496K-GC when strength drives the design. Pick CC496K-GS when the part is bent, formed or impact-loaded.
