Copper Alloy C94400-M01 vs C94400-M07
Copper Alloy · C94400 temper comparison
C94400-M01 and C94400-M07 are two conditions of the same copper alloy grade, C94400: M01 (as sand cast) versus M07 (as continuous cast). The chemistry is identical, so every difference below comes from the condition. C94400-M07 is the stronger of the two: yield strength 124 MPa (18 ksi) against 110 MPa (16 ksi) for C94400-M01, about 13% more; tensile strength follows at 241 MPa (35 ksi) vs 221 MPa (32.1 ksi). In exchange, C94400-M01 is the more ductile: elongation 18% versus 15% for C94400-M07, and C94400-M07 is harder (65 HB vs 55 HB).
C94400-M01Choose it when the part is bent, formed or impact-loaded.
C94400-M07Choose it when strength drives the design.
C94400-M01 vs C94400-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.
