Copper Alloy C89320-M01 vs C89320-M04
Copper Alloy · C89320 temper comparison
C89320-M01 and C89320-M04 are two conditions of the same copper alloy grade, C89320: M01 (as sand cast) versus M04 (as pressure die cast). The chemistry is identical, so every difference below comes from the condition. C89320-M04 is the stronger of the two: yield strength 131 MPa (19 ksi) against 117 MPa (17 ksi) for C89320-M01, about 12% more; tensile strength follows at 255 MPa (37 ksi) vs 241 MPa (35 ksi). C89320-M04 is harder — 65 HB against 60 HB for C89320-M01 — which matters for wear surfaces and threads.
C89320-M04Choose it when strength drives the design, or when surface hardness matters.
C89320-M01 vs C89320-M04: 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.
