Copper Alloy CC334G-GS vs CC334G-GZ
Copper Alloy · CC334G temper comparison
CC334G-GS and CC334G-GZ are two conditions of the same copper alloy grade, CC334G: GS (sand cast) versus GZ (centrifugally cast). The chemistry is identical, so every difference below comes from the condition. CC334G-GZ is the stronger of the two: yield strength 490 MPa (71.1 ksi) against 450 MPa (65.3 ksi) for CC334G-GS, about 9% more; tensile strength follows at 760 MPa (110 ksi) vs 710 MPa (103 ksi). In exchange, CC334G-GS is the more ductile: elongation 6% versus 5% for CC334G-GZ, and CC334G-GZ is harder (265 HB vs 250 HB).
CC334G-GSChoose it when the part is bent, formed or impact-loaded.
CC334G-GZChoose it when strength drives the design.
CC334G-GS vs CC334G-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.
