Copper Alloy CC383H-GS vs CC383H-GZ
Copper Alloy · CC383H temper comparison
CC383H-GS and CC383H-GZ are two conditions of the same copper alloy grade, CC383H: GS (sand cast, as-cast) versus GZ (centrifugally cast). The chemistry is identical, so every difference below comes from the condition. CC383H-GZ is the stronger of the two: yield strength 310 MPa (45 ksi) against 290 MPa (42.1 ksi) for CC383H-GS, about 7% more; tensile strength follows at 510 MPa (74 ksi) vs 480 MPa (69.6 ksi). CC383H-GZ is harder — 150 HB against 140 HB for CC383H-GS — which matters for wear surfaces and threads.
CC383H-GZChoose it when strength drives the design, or when surface hardness matters.
CC383H-GS vs CC383H-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.

CC383H-GS vs CC383H-GZ — frequently asked
Is CC383H-GZ stronger than CC383H-GS?
Yes. CC383H-GZ has a typical yield strength of 310 MPa (45 ksi) against 290 MPa (42.1 ksi) for CC383H-GS — about 7% more. Tensile strength is 510 MPa (74 ksi) vs 480 MPa (69.6 ksi).
Which condition does FabDigit quote by default, GS or GZ?
GS is the default CC383H 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 CC383H-GS over CC383H-GZ?
Pick CC383H-GZ when strength drives the design, or when surface hardness matters.
