Copper Alloy CC496K-GC vs CC496K-GZ

Copper Alloy · CC496K temper comparison

CC496K-GC and CC496K-GZ are two conditions of the same copper alloy grade, CC496K: 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 110 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). CC496K-GC is the more ductile: elongation 9% versus 8% for CC496K-GZ, and CC496K-GC is harder (28 HRB vs 25 HRB).

CC496K-GCChoose it when the part is bent, formed or impact-loaded.

CC496K-GC vs CC496K-GZ — frequently asked

What is the difference between CC496K-GC and CC496K-GZ?

CC496K-GC and CC496K-GZ are two conditions of the same copper alloy grade, CC496K: 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 110 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?

GC is the default CC496K 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 CC496K-GC over CC496K-GZ?

Pick CC496K-GC when the part is bent, formed or impact-loaded.
