Copper Alloy CC760S-GS vs CC760S-GZ

Copper Alloy · CC760S temper comparison

CC760S-GS and CC760S-GZ are two conditions of the same copper alloy grade, CC760S: GS (sand cast) versus GZ (centrifugally cast). The chemistry is identical, so every difference below comes from the condition. CC760S-GZ is the stronger of the two: yield strength 100 MPa (14.5 ksi) against 90 MPa (13.1 ksi) for CC760S-GS, about 11% more; tensile strength follows at 260 MPa (37.7 ksi) vs 220 MPa (31.9 ksi). CC760S-GZ is the more ductile: elongation 35% versus 30% for CC760S-GS, and CC760S-GZ is harder (62 HB vs 55 HB).

CC760S-GZChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.

CC760S-GS vs CC760S-GZ — frequently asked

Is CC760S-GZ stronger than CC760S-GS?

Yes. CC760S-GZ has a typical yield strength of 100 MPa (14.5 ksi) against 90 MPa (13.1 ksi) for CC760S-GS — about 11% more. Tensile strength is 260 MPa (37.7 ksi) vs 220 MPa (31.9 ksi).

Which condition does FabDigit quote by default, GS or GZ?

GS is the default CC760S 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 CC760S-GS over CC760S-GZ?

Pick CC760S-GZ when strength drives the design, or when the part is bent, formed or impact-loaded.
