Copper Alloy CC762S-GS vs CC762S-GZ
Copper Alloy · CC762S temper comparison
CC762S-GS and CC762S-GZ are two conditions of the same copper alloy grade, CC762S: GS (sand cast) versus GZ (centrifugally cast). The chemistry is identical, so every difference below comes from the condition. Both yield at about 470 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (sand cast versus centrifugally cast). For most parts the choice follows the drawing's specified condition; ask for the one your standard calls out.
CC762S-GS vs CC762S-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.

CC762S-GS vs CC762S-GZ — frequently asked
What is the difference between CC762S-GS and CC762S-GZ?
CC762S-GS and CC762S-GZ are two conditions of the same copper alloy grade, CC762S: GS (sand cast) versus GZ (centrifugally cast). The chemistry is identical, so every difference below comes from the condition. Both yield at about 470 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (sand cast versus centrifugally cast).
Which condition does FabDigit quote by default, GS or GZ?
GS is the default CC762S 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.
