Copper Alloy C92900-M01 vs C92900-M07
Copper Alloy · C92900 temper comparison
C92900-M01 and C92900-M07 are two conditions of the same copper alloy grade, C92900: M01 (as sand cast) versus M07 (as continuous cast). The chemistry is identical, so every difference below comes from the condition. C92900-M07 is the stronger of the two: yield strength 220 MPa (31.9 ksi) against 180 MPa (26.1 ksi) for C92900-M01, about 22% more; tensile strength follows at 345 MPa (50 ksi) vs 325 MPa (47.1 ksi). C92900-M07 is the more ductile: elongation 10% versus 8% for C92900-M01, and C92900-M07 is harder (60 HRB vs 56 HRB).
C92900-M07Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
C92900-M01 vs C92900-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.

C92900-M01 vs C92900-M07 — frequently asked
Is C92900-M07 stronger than C92900-M01?
Yes. C92900-M07 has a typical yield strength of 220 MPa (31.9 ksi) against 180 MPa (26.1 ksi) for C92900-M01 — about 22% more. Tensile strength is 345 MPa (50 ksi) vs 325 MPa (47.1 ksi).
Which condition does FabDigit quote by default, M01 or M07?
M07 is the default C92900 condition in the FabDigit quote flow. 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 C92900-M01 over C92900-M07?
Pick C92900-M07 when strength drives the design, or when the part is bent, formed or impact-loaded.
