Copper Alloy C80300-M01 vs C80300-M05
Copper Alloy · C80300 temper comparison
C80300-M01 and C80300-M05 are two conditions of the same copper alloy grade, C80300: M01 (as sand cast) versus M05 (as plaster cast). The chemistry is identical, so every difference below comes from the condition. C80300-M05 is the stronger of the two: yield strength 69 MPa (10 ksi) against 62 MPa (8.99 ksi) for C80300-M01, about 11% more; tensile strength follows at 190 MPa (27.6 ksi) vs 172 MPa (24.9 ksi). C80300-M05 is harder — 48 HB against 44 HB for C80300-M01 — which matters for wear surfaces and threads.
C80300-M05Choose it when strength drives the design, or when surface hardness matters.
C80300-M01 vs C80300-M05: 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.
