Copper Alloy C80100-M02 vs C80100-M07
Copper Alloy · C80100 temper comparison
C80100-M02 and C80100-M07 are two conditions of the same copper alloy grade, C80100: M02 (as centrifugally cast) versus M07 (as continuous cast). The chemistry is identical, so every difference below comes from the condition. C80100-M07 is the stronger of the two: yield strength 90 MPa (13.1 ksi) against 70 MPa (10.2 ksi) for C80100-M02, about 29% more; tensile strength follows at 200 MPa (29 ksi) vs 185 MPa (26.8 ksi). In exchange, C80100-M02 is the more ductile: elongation 40% versus 35% for C80100-M07, and C80100-M07 is harder (55 HB vs 46 HB).
C80100-M02Choose it when the part is bent, formed or impact-loaded.
C80100-M07Choose it when strength drives the design.
C80100-M02 vs C80100-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.

C80100-M02 vs C80100-M07 — frequently asked
Is C80100-M07 stronger than C80100-M02?
Yes. C80100-M07 has a typical yield strength of 90 MPa (13.1 ksi) against 70 MPa (10.2 ksi) for C80100-M02 — about 29% more. Tensile strength is 200 MPa (29 ksi) vs 185 MPa (26.8 ksi).
Which condition does FabDigit quote by default, M02 or M07?
M01 is the default C80100 condition in the FabDigit quote flow (neither M02 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 C80100-M02 over C80100-M07?
Pick C80100-M02 when the part is bent, formed or impact-loaded. Pick C80100-M07 when strength drives the design.
