Copper Alloy C84100-M01 vs C84100-M07
Copper Alloy · C84100 temper comparison
C84100-M01 and C84100-M07 are two conditions of the same copper alloy grade, C84100: M01 (as sand cast) versus M07 (as continuous cast). The chemistry is identical, so every difference below comes from the condition. C84100-M07 is the stronger of the two: yield strength 110 MPa (16 ksi) against 90 MPa (13.1 ksi) for C84100-M01, about 22% more; tensile strength follows at 234 MPa (33.9 ksi) vs 207 MPa (30 ksi). C84100-M07 is harder — 58 HB against 52 HB for C84100-M01 — which matters for wear surfaces and threads.
C84100-M07Choose it when strength drives the design, or when surface hardness matters.
C84100-M01 vs C84100-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.
