Copper Alloy CC752S-GC vs CC752S-GS
Copper Alloy · CC752S temper comparison
CC752S-GC and CC752S-GS are two conditions of the same copper alloy grade, CC752S: GC (continuously cast) versus GS (sand cast). The chemistry is identical, so every difference below comes from the condition. CC752S-GC is the stronger of the two: yield strength 150 MPa (21.8 ksi) against 110 MPa (16 ksi) for CC752S-GS, about 36% more; tensile strength follows at 320 MPa (46.4 ksi) vs 280 MPa (40.6 ksi). In exchange, CC752S-GS is the more ductile: elongation 15% versus 12% for CC752S-GC, and CC752S-GC is harder (90 HB vs 75 HB). CC752S-GC is stiffer (100 GPa vs 95 GPa).
CC752S-GCChoose it when strength drives the design.
CC752S-GSChoose it when the part is bent, formed or impact-loaded.
CC752S-GC vs CC752S-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.

CC752S-GC vs CC752S-GS — frequently asked
Is CC752S-GC stronger than CC752S-GS?
Yes. CC752S-GC has a typical yield strength of 150 MPa (21.8 ksi) against 110 MPa (16 ksi) for CC752S-GS — about 36% more. Tensile strength is 320 MPa (46.4 ksi) vs 280 MPa (40.6 ksi).
Which condition does FabDigit quote by default, GC or GS?
GS is the default CC752S 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 CC752S-GC over CC752S-GS?
Pick CC752S-GC when strength drives the design. Pick CC752S-GS when the part is bent, formed or impact-loaded.
