Copper Alloy C84800 vs CC481K
Copper Alloy · grade comparison
Copper Alloy C84800 and CC481K are both copper alloy grades. CC481K is the stronger of the two: yield strength 230 MPa (33.4 ksi) against 124 MPa (18 ksi) for C84800, about 85% more; tensile strength follows at 380 MPa (55.1 ksi) vs 262 MPa (38 ksi). In exchange, C84800 is the more ductile: elongation 35% versus 8% for CC481K, and CC481K is harder (105 HB vs 55 HB). CC481K is stiffer (110 GPa vs 86 GPa) and CC481K runs hotter in service (250°C vs 200°C continuous). On the shop floor, C84800 machines more easily (excellent vs fair) and CC481K sits in a lower cost tier (high, $$$$) than C84800 (specialty, $$$$$).
C84800Choose it when the part is bent, formed or impact-loaded, or when the part is machined in volume.
CC481KChoose it when strength drives the design, or when the part sees heat.
C84800 vs CC481K: 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.
