Copper Alloy C86800-M01 vs C86800-M07
Copper Alloy · C86800 temper comparison
C86800-M01 and C86800-M07 are two conditions of the same copper alloy grade, C86800: M01 (as sand cast) versus M07 (as continuous cast). The chemistry is identical, so every difference below comes from the condition. C86800-M07 is the stronger of the two: yield strength 315 MPa (45.7 ksi) against 290 MPa (42.1 ksi) for C86800-M01, about 9% more; tensile strength follows at 600 MPa (87 ksi) vs 565 MPa (81.9 ksi). In exchange, C86800-M01 is the more ductile: elongation 20% versus 18% for C86800-M07, and C86800-M07 is harder (160 HB vs 150 HB).
C86800-M01Choose it when the part is bent, formed or impact-loaded.
C86800-M07Choose it when strength drives the design.
C86800-M01 vs C86800-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.
