Copper Alloy CC484K-GC vs CC484K-GZ

Copper Alloy · CC484K temper comparison

CC484K-GC and CC484K-GZ are two conditions of the same copper alloy grade, CC484K: GC (continuously cast bar / tube) versus GZ (centrifugally cast). The chemistry is identical, so every difference below comes from the condition. Both yield at about 205 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (continuously cast bar / tube versus centrifugally cast). For most parts the choice follows the drawing's specified condition; ask for the one your standard calls out.

CC484K-GC vs CC484K-GZ — frequently asked

What is the difference between CC484K-GC and CC484K-GZ?

CC484K-GC and CC484K-GZ are two conditions of the same copper alloy grade, CC484K: GC (continuously cast bar / tube) versus GZ (centrifugally cast). The chemistry is identical, so every difference below comes from the condition. Both yield at about 205 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (continuously cast bar / tube versus centrifugally cast).

Which condition does FabDigit quote by default, GC 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.

Which is easier to machine, CC484K-GC or CC484K-GZ?

CC484K-GC, by a small margin. Both rate fair for machinability — 50/100 against 45/100 for CC484K-GZ.
