Copper Alloy C84800 vs C92300
Copper Alloy · grade comparison
Copper Alloy C84800 and C92300 are both copper alloy grades. C92300 is the stronger of the two: tensile strength 276 MPa (40 ksi) against 262 MPa (38 ksi) for C84800, about 5% more. In exchange, C84800 is the more ductile: elongation 35% versus 25% for C92300, and C92300 is harder (70 HB vs 55 HB). C92300 is stiffer (100 GPa vs 86 GPa) and C92300 runs hotter in service (260°C vs 200°C continuous). On the shop floor, C84800 machines more easily (excellent vs very good), C92300 welds better (30 vs 20 out of 100), and C92300 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.
C92300Choose it when strength drives the design, or when the part sees heat.
C84800 vs C92300: 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.
