Copper Alloy C84200 vs CC490K
Copper Alloy · grade comparison
Copper Alloy C84200 and CC490K are both copper alloy grades. C84200 is the stronger of the two: tensile strength 241 MPa (35 ksi) against 215 MPa (31.2 ksi) for CC490K, about 12% more. C84200 is the more ductile: elongation 27% versus 20% for CC490K, and CC490K is harder (65 HB vs 55 HB). C84200 is stiffer (95 GPa vs 90 GPa).
C84200Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
C84200 vs CC490K: 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.

C84200 vs CC490K — frequently asked
Is C84200 stronger than CC490K?
Yes. C84200 has a typical tensile strength of 241 MPa (35 ksi) against 215 MPa (31.2 ksi) for CC490K — about 12% more.
Which is cheaper, C84200 or CC490K?
Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which welds better, C84200 or CC490K?
CC490K. Its weldability rates poor (25/100) against poor (20/100) for C84200.
