Copper Alloy C91600-M01 vs C91600-M07
Copper Alloy · C91600 temper comparison
C91600-M01 and C91600-M07 are two conditions of the same copper alloy grade, C91600: M01 (as sand cast) versus M07 (as continuous cast). The chemistry is identical, so every difference below comes from the condition. C91600-M07 is the stronger of the two: yield strength 172 MPa (24.9 ksi) against 152 MPa (22 ksi) for C91600-M01, about 13% more. In exchange, C91600-M01 is the more ductile: elongation 16% versus 10% for C91600-M07, and C91600-M07 is harder (105 HB vs 90 HB).
C91600-M01Choose it when the part is bent, formed or impact-loaded.
C91600-M07Choose it when strength drives the design.
C91600-M01 vs C91600-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.
