Copper Alloy CC382H-GC vs CC382H-GS
Copper Alloy · CC382H temper comparison
CC382H-GC and CC382H-GS are two conditions of the same copper alloy grade, CC382H: GC (continuously cast bar/tube) versus GS (sand cast, as-cast). The chemistry is identical, so every difference below comes from the condition. CC382H-GC is the stronger of the two: yield strength 310 MPa (45 ksi) against 275 MPa (39.9 ksi) for CC382H-GS, about 13% more; tensile strength follows at 500 MPa (72.5 ksi) vs 470 MPa (68.2 ksi). CC382H-GC is harder — 140 HB against 130 HB for CC382H-GS — which matters for wear surfaces and threads.
CC382H-GCChoose it when strength drives the design, or when surface hardness matters.
CC382H-GC vs CC382H-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.

CC382H-GC vs CC382H-GS — frequently asked
Is CC382H-GC stronger than CC382H-GS?
Yes. CC382H-GC has a typical yield strength of 310 MPa (45 ksi) against 275 MPa (39.9 ksi) for CC382H-GS — about 13% more. Tensile strength is 500 MPa (72.5 ksi) vs 470 MPa (68.2 ksi).
Which condition does FabDigit quote by default, GC or GS?
GS is the default CC382H 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 CC382H-GC over CC382H-GS?
Pick CC382H-GC when strength drives the design, or when surface hardness matters.
