Copper Alloy CC753S-GC vs CC753S-GZ
Copper Alloy · CC753S temper comparison
CC753S-GC and CC753S-GZ are two conditions of the same copper alloy grade, CC753S: GC (continuously cast bar/tube) versus GZ (centrifugally cast). The chemistry is identical, so every difference below comes from the condition. CC753S-GC is the stronger of the two: yield strength 200 MPa (29 ksi) against 190 MPa (27.6 ksi) for CC753S-GZ, about 5% more.
CC753S-GCChoose it when strength drives the design.
CC753S-GC vs CC753S-GZ: 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.

CC753S-GC vs CC753S-GZ — frequently asked
Is CC753S-GC stronger than CC753S-GZ?
Yes. CC753S-GC has a typical yield strength of 200 MPa (29 ksi) against 190 MPa (27.6 ksi) for CC753S-GZ — about 5% more. Tensile strength is 390 MPa (56.6 ksi) vs 390 MPa (56.6 ksi).
Which condition does FabDigit quote by default, GC or GZ?
GS is the default CC753S condition in the FabDigit quote flow (neither GC nor GZ). 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, CC753S-GC or CC753S-GZ?
CC753S-GC, by a small margin. Both rate very good for machinability — 82/100 against 76/100 for CC753S-GZ.
