Copper Alloy C64200-M10 vs C64200-O60
Copper Alloy · C64200 temper comparison
C64200-M10 and C64200-O60 are two conditions of the same copper alloy grade, C64200: M10 (as hot forged and air cooled) versus O60 (soft annealed). The chemistry is identical, so every difference below comes from the condition. C64200-M10 is the stronger of the two: yield strength 270 MPa (39.2 ksi) against 205 MPa (29.7 ksi) for C64200-O60, about 32% more; tensile strength follows at 550 MPa (79.8 ksi) vs 485 MPa (70.3 ksi). In exchange, C64200-O60 is the more ductile: elongation 35% versus 28% for C64200-M10, and C64200-M10 is harder (150 HB vs 110 HB). C64200-O60 runs hotter in service (300°C vs 250°C continuous).
C64200-M10Choose it when strength drives the design.
C64200-O60Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C64200-M10 vs C64200-O60: 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-M10 vs C64200-O60 — frequently asked
Is C64200-M10 stronger than C64200-O60?
Yes. C64200-M10 has a typical yield strength of 270 MPa (39.2 ksi) against 205 MPa (29.7 ksi) for C64200-O60 — about 32% more. Tensile strength is 550 MPa (79.8 ksi) vs 485 MPa (70.3 ksi).
Which condition does FabDigit quote by default, M10 or O60?
HR50 is the default C64200 condition in the FabDigit quote flow (neither M10 nor O60). 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 is easier to machine, C64200-M10 or C64200-O60?
C64200-M10. Its machinability rates good (55/100) against fair (48/100) for C64200-O60.
