Copper Alloy C96900-M02 vs C96900-M07
Copper Alloy · C96900 temper comparison
C96900-M02 and C96900-M07 are two conditions of the same copper alloy grade, C96900: M02 (as centrifugally cast) versus M07 (as continuous cast). The chemistry is identical, so every difference below comes from the condition. C96900-M07 is the stronger of the two: yield strength 275 MPa (39.9 ksi) against 260 MPa (37.7 ksi) for C96900-M02, about 6% more; tensile strength follows at 550 MPa (79.8 ksi) vs 520 MPa (75.4 ksi). C96900-M07 is the more ductile: elongation 18% versus 15% for C96900-M02, and C96900-M07 is harder (180 HB vs 170 HB).
C96900-M07Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
C96900-M02 vs C96900-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.

C96900-M02 vs C96900-M07 — frequently asked
Is C96900-M07 stronger than C96900-M02?
Yes. C96900-M07 has a typical yield strength of 275 MPa (39.9 ksi) against 260 MPa (37.7 ksi) for C96900-M02 — about 6% more. Tensile strength is 550 MPa (79.8 ksi) vs 520 MPa (75.4 ksi).
Which condition does FabDigit quote by default, M02 or M07?
TX00 is the default C96900 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 C96900-M02 over C96900-M07?
Pick C96900-M07 when strength drives the design, or when the part is bent, formed or impact-loaded.
