Copper Alloy C94300-M01 vs C94300-M02
Copper Alloy · C94300 temper comparison
C94300-M01 and C94300-M02 are two conditions of the same copper alloy grade, C94300: M01 (as sand cast) versus M02 (as centrifugally cast). The chemistry is identical, so every difference below comes from the condition. C94300-M02 is the stronger of the two: yield strength 100 MPa (14.5 ksi) against 90 MPa (13.1 ksi) for C94300-M01, about 11% more; tensile strength follows at 200 MPa (29 ksi) vs 186 MPa (27 ksi). In exchange, C94300-M01 is the more ductile: elongation 15% versus 12% for C94300-M02, and C94300-M02 is harder (52 HB vs 48 HB).
C94300-M01Choose it when the part is bent, formed or impact-loaded.
C94300-M02Choose it when strength drives the design.
C94300-M01 vs C94300-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.

C94300-M01 vs C94300-M02 — frequently asked
Is C94300-M02 stronger than C94300-M01?
Yes. C94300-M02 has a typical yield strength of 100 MPa (14.5 ksi) against 90 MPa (13.1 ksi) for C94300-M01 — about 11% more. Tensile strength is 200 MPa (29 ksi) vs 186 MPa (27 ksi).
Which condition does FabDigit quote by default, M01 or M02?
M07 is the default C94300 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 C94300-M01 over C94300-M02?
Pick C94300-M01 when the part is bent, formed or impact-loaded. Pick C94300-M02 when strength drives the design.
