Copper Alloy C83600 vs CC490K
Copper Alloy · grade comparison
Copper Alloy C83600 and CC490K are both copper alloy grades. C83600 is the stronger of the two: yield strength 117 MPa (17 ksi) against 100 MPa (14.5 ksi) for CC490K, about 17% more; tensile strength follows at 255 MPa (37 ksi) vs 215 MPa (31.2 ksi). C83600 is the more ductile: elongation 30% versus 20% for CC490K, and CC490K is harder (65 HB vs 60 HB). CC490K is stiffer (90 GPa vs 83 GPa).
C83600Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
C83600 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.

C83600 vs CC490K — frequently asked
Is C83600 stronger than CC490K?
Yes. C83600 has a typical yield strength of 117 MPa (17 ksi) against 100 MPa (14.5 ksi) for CC490K — about 17% more. Tensile strength is 255 MPa (37 ksi) vs 215 MPa (31.2 ksi).
Which is cheaper, C83600 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, C83600 or CC490K?
CC490K. Its weldability rates poor (25/100) against poor (20/100) for C83600.
