Copper Alloy CC490K vs YBsC3
Copper Alloy · grade comparison
Copper Alloy CC490K and YBsC3 are both copper alloy grades. YBsC3 is the stronger of the two: tensile strength 295 MPa (42.8 ksi) against 215 MPa (31.2 ksi) for CC490K, about 37% more. YBsC3 is the more ductile: elongation 25% versus 20% for CC490K, and YBsC3 is harder (70 HB vs 65 HB). YBsC3 is lighter (8.4 g/cm³ vs 8.7 g/cm³ for CC490K) and YBsC3 is stiffer (96 GPa vs 90 GPa). On the shop floor, YBsC3 sits in a lower cost tier (premium, $$$) than CC490K (high, $$$$).
YBsC3Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
CC490K vs YBsC3: 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.
