Copper Alloy C64210-H04 vs C64210-M10
Copper Alloy · C64210 temper comparison
C64210-H04 and C64210-M10 are two conditions of the same copper alloy grade, C64210: H04 (full hard) versus M10 (as hot forged and air cooled). The chemistry is identical, so every difference below comes from the condition. C64210-H04 is the stronger of the two: yield strength 393 MPa (57 ksi) against 250 MPa (36.3 ksi) for C64210-M10, about 57% more; tensile strength follows at 655 MPa (95 ksi) vs 552 MPa (80.1 ksi). In exchange, C64210-M10 is the more ductile: elongation 30% versus 22% for C64210-H04, and C64210-H04 is harder (180 HB vs 150 HB). C64210-M10 runs hotter in service (300°C vs 260°C continuous).
C64210-H04Choose it when strength drives the design.
C64210-M10Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C64210-H04 vs C64210-M10: 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.
