Copper Alloy C84500-M05 vs C84500-M06
Copper Alloy · C84500 temper comparison
C84500-M05 and C84500-M06 are two conditions of the same copper alloy grade, C84500: M05 (as plaster cast) versus M06 (as investment cast). The chemistry is identical, so every difference below comes from the condition. C84500-M05 is the stronger of the two: yield strength 117 MPa (17 ksi) against 103 MPa (14.9 ksi) for C84500-M06, about 14% more; tensile strength follows at 255 MPa (37 ksi) vs 241 MPa (35 ksi). In exchange, C84500-M06 is the more ductile: elongation 25% versus 20% for C84500-M05, and C84500-M05 is harder (60 HB vs 55 HB).
C84500-M05Choose it when strength drives the design.
C84500-M06Choose it when the part is bent, formed or impact-loaded.
C84500-M05 vs C84500-M06: 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.

C84500-M05 vs C84500-M06 — frequently asked
Is C84500-M05 stronger than C84500-M06?
Yes. C84500-M05 has a typical yield strength of 117 MPa (17 ksi) against 103 MPa (14.9 ksi) for C84500-M06 — about 14% more. Tensile strength is 255 MPa (37 ksi) vs 241 MPa (35 ksi).
Which condition does FabDigit quote by default, M05 or M06?
M01 is the default C84500 condition in the FabDigit quote flow (neither M05 nor M06). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
When should I choose C84500-M05 over C84500-M06?
Pick C84500-M05 when strength drives the design. Pick C84500-M06 when the part is bent, formed or impact-loaded.
