Copper Alloy C84200-M01 vs C84200-M05
Copper Alloy · C84200 temper comparison
C84200-M01 and C84200-M05 are two conditions of the same copper alloy grade, C84200: M01 (as sand cast) versus M05 (as plaster cast). The chemistry is identical, so every difference below comes from the condition. C84200-M05 is the stronger of the two: yield strength 110 MPa (16 ksi) against 103 MPa (14.9 ksi) for C84200-M01, about 7% more; tensile strength follows at 255 MPa (37 ksi) vs 241 MPa (35 ksi). In exchange, C84200-M01 is the more ductile: elongation 27% versus 24% for C84200-M05, and C84200-M05 is harder (58 HB vs 55 HB).
C84200-M01Choose it when the part is bent, formed or impact-loaded.
C84200-M05Choose it when strength drives the design.
C84200-M01 vs C84200-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.
