Copper Alloy C95400 vs C95500
Copper Alloy · grade comparison
Copper Alloy C95400 and C95500 are both copper alloy grades. C95500 is the stronger of the two: yield strength 300 MPa (43.5 ksi) against 241 MPa (35 ksi) for C95400, about 24% more; tensile strength follows at 700 MPa (102 ksi) vs 586 MPa (85 ksi). In exchange, C95400 is the more ductile: elongation 12% versus 8% for C95500, and C95500 is harder (192 HB vs 170 HB). C95400 conducts heat better (58.6 W/m·K vs 42 W/m·K).
C95400Choose it when the part is bent, formed or impact-loaded.
C95500Choose it when strength drives the design.
C95400 vs C95500: 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.

C95400 vs C95500 — frequently asked
Is C95500 stronger than C95400?
Yes. C95500 has a typical yield strength of 300 MPa (43.5 ksi) against 241 MPa (35 ksi) for C95400 — about 24% more. Tensile strength is 700 MPa (102 ksi) vs 586 MPa (85 ksi).
Which is cheaper, C95400 or C95500?
Both sit in the same relative cost tier ($$$$$, specialty); the part price will be decided by machining time, tolerance and quantity rather than by the material.
Which is easier to machine, C95400 or C95500?
C95400, by a small margin. Both rate fair for machinability — 48/100 against 40/100 for C95500.
