Copper Alloy CC484K-GM vs CC484K-GZ
Copper Alloy · CC484K temper comparison
CC484K-GM and CC484K-GZ are two conditions of the same copper alloy grade, CC484K: GM (chill / permanent-mould (gravity die) cast) versus GZ (centrifugally cast). The chemistry is identical, so every difference below comes from the condition. Both yield at about 195 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (chill / permanent-mould (gravity die) cast versus centrifugally cast). CC484K-GZ is the more ductile: elongation 10% versus 9% for CC484K-GM, and CC484K-GZ is harder (60 HRB vs 56 HRB).

CC484K-GM vs CC484K-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.

What is the difference between CC484K-GM and CC484K-GZ?
CC484K-GM and CC484K-GZ are two conditions of the same copper alloy grade, CC484K: GM (chill / permanent-mould (gravity die) cast) versus GZ (centrifugally cast). The chemistry is identical, so every difference below comes from the condition. Both yield at about 195 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (chill / permanent-mould (gravity die) cast versus centrifugally cast).
Which condition does FabDigit quote by default, GM or GZ?
GZ is the default CC484K 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 CC484K-GM over CC484K-GZ?
Pick CC484K-GZ when the part is bent, formed or impact-loaded.
