Copper Alloy CC484K-GM vs CC484K-GS
Copper Alloy · CC484K temper comparison
CC484K-GM and CC484K-GS are two conditions of the same copper alloy grade, CC484K: GM (chill / permanent-mould (gravity die) cast) versus GS (sand cast). The chemistry is identical, so every difference below comes from the condition. CC484K-GM is the stronger of the two: yield strength 195 MPa (28.3 ksi) against 175 MPa (25.4 ksi) for CC484K-GS, about 11% more; tensile strength follows at 320 MPa (46.4 ksi) vs 300 MPa (43.5 ksi). In exchange, CC484K-GS is the more ductile: elongation 10% versus 9% for CC484K-GM, and CC484K-GM is harder (100 HB vs 95 HB).
CC484K-GMChoose it when strength drives the design.
CC484K-GSChoose it when the part is bent, formed or impact-loaded.
CC484K-GM vs CC484K-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.

CC484K-GM vs CC484K-GS — frequently asked
Is CC484K-GM stronger than CC484K-GS?
Yes. CC484K-GM has a typical yield strength of 195 MPa (28.3 ksi) against 175 MPa (25.4 ksi) for CC484K-GS — about 11% more. Tensile strength is 320 MPa (46.4 ksi) vs 300 MPa (43.5 ksi).
Which condition does FabDigit quote by default, GM or GS?
GZ is the default CC484K condition in the FabDigit quote flow (neither GM nor GS). 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 CC484K-GM over CC484K-GS?
Pick CC484K-GM when strength drives the design. Pick CC484K-GS when the part is bent, formed or impact-loaded.
