Copper Alloy CC482K-GC vs CC482K-GZ
Copper Alloy · CC482K temper comparison
CC482K-GC and CC482K-GZ are two conditions of the same copper alloy grade, CC482K: GC (continuous cast bar/tube) versus GZ (centrifugal cast). The chemistry is identical, so every difference below comes from the condition. CC482K-GZ is the stronger of the two: yield strength 185 MPa (26.8 ksi) against 170 MPa (24.7 ksi) for CC482K-GC, about 9% more; tensile strength follows at 320 MPa (46.4 ksi) vs 300 MPa (43.5 ksi). In exchange, CC482K-GC is the more ductile: elongation 8% versus 7% for CC482K-GZ, and CC482K-GZ is harder (100 HB vs 95 HB).
CC482K-GCChoose it when the part is bent, formed or impact-loaded.
CC482K-GZChoose it when strength drives the design.
CC482K-GC vs CC482K-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.

CC482K-GC vs CC482K-GZ — frequently asked
Is CC482K-GZ stronger than CC482K-GC?
Yes. CC482K-GZ has a typical yield strength of 185 MPa (26.8 ksi) against 170 MPa (24.7 ksi) for CC482K-GC — about 9% more. Tensile strength is 320 MPa (46.4 ksi) vs 300 MPa (43.5 ksi).
Which condition does FabDigit quote by default, GC or GZ?
GC is the default CC482K 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.
Which is easier to machine, CC482K-GC or CC482K-GZ?
CC482K-GC, by a small margin. Both rate good for machinability — 60/100 against 55/100 for CC482K-GZ.
