Copper Alloy C10100 vs C80900
Copper Alloy · grade comparison
Copper Alloy C10100 and C80900 are both copper alloy grades. C10100 is the stronger of the two: yield strength 69 MPa (10 ksi) against 62 MPa (8.99 ksi) for C80900, about 11% more; tensile strength follows at 235 MPa (34.1 ksi) vs 172 MPa (24.9 ksi). C10100 is the more ductile: elongation 45% versus 40% for C80900, and C10100 is harder (50 HV vs 46 HV). C10100 conducts heat better (391 W/m·K vs 350 W/m·K). On the shop floor, C80900 sits in a lower cost tier (high, $$$$) than C10100 (specialty, $$$$$).
C10100Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
C80900Choose it when cost is the deciding factor.
C10100 vs C80900: 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.
