Copper Alloy C94300-M05 vs C94300-M07
Copper Alloy · C94300 temper comparison
C94300-M05 and C94300-M07 are two conditions of the same copper alloy grade, C94300: M05 (as plaster cast) versus M07 (as continuous cast). The chemistry is identical, so every difference below comes from the condition. Both yield at about 100 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (as plaster cast versus as continuous cast). C94300-M07 is harder — 55 HB against 52 HB for C94300-M05 — which matters for wear surfaces and threads.
C94300-M07Choose it when surface hardness matters.
C94300-M05 vs C94300-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.
