Copper Alloy C64200-H04 vs C64200-M10
Copper Alloy · C64200 temper comparison
C64200-H04 and C64200-M10 are two conditions of the same copper alloy grade, C64200: H04 (full hard) versus M10 (as hot forged and air cooled). The chemistry is identical, so every difference below comes from the condition. C64200-H04 is the stronger of the two: yield strength 415 MPa (60.2 ksi) against 270 MPa (39.2 ksi) for C64200-M10, about 54% more; tensile strength follows at 725 MPa (105 ksi) vs 550 MPa (79.8 ksi). In exchange, C64200-M10 is the more ductile: elongation 28% versus 22% for C64200-H04, and C64200-H04 is harder (200 HB vs 150 HB).

C64200-M10Choose it when the part is bent, formed or impact-loaded.
C64200-H04 vs C64200-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.

C64200-H04 vs C64200-M10 — frequently asked
Is C64200-H04 stronger than C64200-M10?
Yes. C64200-H04 has a typical yield strength of 415 MPa (60.2 ksi) against 270 MPa (39.2 ksi) for C64200-M10 — about 54% more. Tensile strength is 725 MPa (105 ksi) vs 550 MPa (79.8 ksi).
Which condition does FabDigit quote by default, H04 or M10?
HR50 is the default C64200 condition in the FabDigit quote flow (neither H04 nor M10). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which welds better, C64200-H04 or C64200-M10?
C64200-M10. Its weldability rates very good (70/100) against good (65/100) for C64200-H04.
