Copper Alloy C93900-M01 vs C93900-M02
Copper Alloy · C93900 temper comparison
C93900-M01 and C93900-M02 are two conditions of the same copper alloy grade, C93900: M01 (as sand cast) versus M02 (as centrifugally cast). The chemistry is identical, so every difference below comes from the condition. Both yield at about 138 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (as sand cast versus as centrifugally cast). C93900-M01 is the more ductile: elongation 7% versus 6% for C93900-M02, and C93900-M02 is harder (70 HV vs 66 HV).
C93900-M01Choose it when the part is bent, formed or impact-loaded.
C93900-M01 vs C93900-M02: 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.

C93900-M01 vs C93900-M02 — frequently asked
What is the difference between C93900-M01 and C93900-M02?
C93900-M01 and C93900-M02 are two conditions of the same copper alloy grade, C93900: M01 (as sand cast) versus M02 (as centrifugally cast). The chemistry is identical, so every difference below comes from the condition. Both yield at about 138 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (as sand cast versus as centrifugally cast).
Which condition does FabDigit quote by default, M01 or M02?
M07 is the default C93900 condition in the FabDigit quote flow (neither M01 nor M02). 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 C93900-M01 over C93900-M02?
Pick C93900-M01 when the part is bent, formed or impact-loaded.
