Copper Alloy C84800 vs C92610
Copper Alloy · grade comparison
Copper Alloy C84800 and C92610 are both copper alloy grades. C92610 is the stronger of the two: yield strength 145 MPa (21 ksi) against 124 MPa (18 ksi) for C84800, about 17% more. In exchange, C84800 is the more ductile: elongation 35% versus 22% for C92610, and C92610 is harder (70 HB vs 55 HB). C92610 is stiffer (100 GPa vs 86 GPa) and C92610 runs hotter in service (260°C vs 200°C continuous). On the shop floor, C92610 sits in a lower cost tier (high, $$$$) than C84800 (specialty, $$$$$).
C84800Choose it when the part is bent, formed or impact-loaded.
C92610Choose it when strength drives the design, or when the part sees heat.
C84800 vs C92610: 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.
