Copper Alloy CC760S-GC vs CC760S-GS
Copper Alloy · CC760S temper comparison
CC760S-GC and CC760S-GS are two conditions of the same copper alloy grade, CC760S: GC (continuously cast bar/tube) versus GS (sand cast). The chemistry is identical, so every difference below comes from the condition. CC760S-GC is the stronger of the two: yield strength 110 MPa (16 ksi) against 90 MPa (13.1 ksi) for CC760S-GS, about 22% more; tensile strength follows at 270 MPa (39.2 ksi) vs 220 MPa (31.9 ksi). CC760S-GC is harder — 65 HB against 55 HB for CC760S-GS — which matters for wear surfaces and threads.
CC760S-GCChoose it when strength drives the design, or when surface hardness matters.
CC760S-GC vs CC760S-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.

CC760S-GC vs CC760S-GS — frequently asked
Is CC760S-GC stronger than CC760S-GS?
Yes. CC760S-GC has a typical yield strength of 110 MPa (16 ksi) against 90 MPa (13.1 ksi) for CC760S-GS — about 22% more. Tensile strength is 270 MPa (39.2 ksi) vs 220 MPa (31.9 ksi).
Which condition does FabDigit quote by default, GC or GS?
GS is the default CC760S 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 CC760S-GC over CC760S-GS?
Pick CC760S-GC when strength drives the design, or when surface hardness matters.
