Copper Alloy C95500 vs CC480K
Copper Alloy · grade comparison
Copper Alloy C95500 and CC480K are both copper alloy grades. C95500 is the stronger of the two: yield strength 300 MPa (43.5 ksi) against 190 MPa (27.6 ksi) for CC480K, about 58% more; tensile strength follows at 700 MPa (102 ksi) vs 330 MPa (47.9 ksi). C95500 is harder — 192 HB against 95 HB for CC480K — which matters for wear surfaces and threads. C95500 is lighter (7.53 g/cm³ vs 8.8 g/cm³ for CC480K) and C95500 is stiffer (110 GPa vs 103 GPa). On the shop floor, C95500 welds better (good vs poor), C95500 forms better (poor vs not recommended), and CC480K sits in a lower cost tier (high, $$$$) than C95500 (specialty, $$$$$).
C95500Choose it when strength drives the design, or when surface hardness matters.
CC480KChoose it when cost is the deciding factor.
C95500 vs CC480K: 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.

C95500 vs CC480K — frequently asked
Is C95500 stronger than CC480K?
Yes. C95500 has a typical yield strength of 300 MPa (43.5 ksi) against 190 MPa (27.6 ksi) for CC480K — about 58% more. Tensile strength is 700 MPa (102 ksi) vs 330 MPa (47.9 ksi).
Which is cheaper, C95500 or CC480K?
CC480K is the lower-cost material: it sits in the high tier ($$$$) while C95500 is specialty ($$$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.
Which is easier to machine, C95500 or CC480K?
CC480K, by a small margin. Both rate fair for machinability — 45/100 against 40/100 for C95500; for welding the order is C95500 first (good, 60/100) then CC480K (poor, 25/100).
