Copper Alloy C94100-M02 vs C94100-M07
Copper Alloy · C94100 temper comparison
C94100-M02 and C94100-M07 are two conditions of the same copper alloy grade, C94100: M02 (as centrifugally cast) versus M07 (as continuous cast). The chemistry is identical, so every difference below comes from the condition. C94100-M07 is the stronger of the two: yield strength 110 MPa (16 ksi) against 100 MPa (14.5 ksi) for C94100-M02, about 10% more; tensile strength follows at 207 MPa (30 ksi) vs 193 MPa (28 ksi).
C94100-M07Choose it when strength drives the design.
C94100-M02 vs C94100-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.

C94100-M02 vs C94100-M07 — frequently asked
Is C94100-M07 stronger than C94100-M02?
Yes. C94100-M07 has a typical yield strength of 110 MPa (16 ksi) against 100 MPa (14.5 ksi) for C94100-M02 — about 10% more. Tensile strength is 207 MPa (30 ksi) vs 193 MPa (28 ksi).
Which condition does FabDigit quote by default, M02 or M07?
M01 is the default C94100 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 C94100-M02 over C94100-M07?
Pick C94100-M07 when strength drives the design.
