Copper Alloy C80500-M03 vs C80500-M07
Copper Alloy · C80500 temper comparison
C80500-M03 and C80500-M07 are two conditions of the same copper alloy grade, C80500: M03 (as chill cast) versus M07 (as continuous cast). The chemistry is identical, so every difference below comes from the condition. C80500-M07 is the stronger of the two: yield strength 78 MPa (11.3 ksi) against 60 MPa (8.7 ksi) for C80500-M03, about 30% more; tensile strength follows at 210 MPa (30.5 ksi) vs 175 MPa (25.4 ksi). In exchange, C80500-M03 is the more ductile: elongation 40% versus 35% for C80500-M07, and C80500-M07 is harder (50 HB vs 43 HB).
C80500-M03Choose it when the part is bent, formed or impact-loaded.
C80500-M07Choose it when strength drives the design.
C80500-M03 vs C80500-M07: 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.

C80500-M03 vs C80500-M07 — frequently asked
Is C80500-M07 stronger than C80500-M03?
Yes. C80500-M07 has a typical yield strength of 78 MPa (11.3 ksi) against 60 MPa (8.7 ksi) for C80500-M03 — about 30% more. Tensile strength is 210 MPa (30.5 ksi) vs 175 MPa (25.4 ksi).
Which condition does FabDigit quote by default, M03 or M07?
M01 is the default C80500 condition in the FabDigit quote flow (neither M03 nor M07). 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 C80500-M03 over C80500-M07?
Pick C80500-M03 when the part is bent, formed or impact-loaded. Pick C80500-M07 when strength drives the design.
