Copper Alloy C95500 vs CC334G
Copper Alloy · grade comparison
Copper Alloy C95500 and CC334G are both copper alloy grades. CC334G is the stronger of the two: yield strength 450 MPa (65.3 ksi) against 300 MPa (43.5 ksi) for C95500, about 50% more. In exchange, C95500 is the more ductile: elongation 8% versus 6% for CC334G, and CC334G is harder (250 HB vs 192 HB). CC334G is stiffer (122 GPa vs 110 GPa) and C95500 conducts electricity better (8.5 % IACS vs 7 % IACS). On the shop floor, C95500 machines more easily (fair vs poor), C95500 welds better (good vs fair), and CC334G sits in a lower cost tier (high, $$$$) than C95500 (specialty, $$$$$).
C95500Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
CC334GChoose it when strength drives the design, or when cost is the deciding factor.
C95500 vs CC334G: 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.
