Copper Alloy C63000-M10 vs C63000-O60
Copper Alloy · C63000 temper comparison
C63000-M10 and C63000-O60 are two conditions of the same copper alloy grade, C63000: M10 (as hot forged and air cooled) versus O60 (soft annealed). The chemistry is identical, so every difference below comes from the condition. C63000-M10 is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 310 MPa (45 ksi) for C63000-O60, about 23% more; tensile strength follows at 690 MPa (100 ksi) vs 655 MPa (95 ksi). In exchange, C63000-O60 is the more ductile: elongation 25% versus 13% for C63000-M10, and C63000-M10 is harder (197 HB vs 150 HB).
C63000-M10Choose it when strength drives the design.
C63000-O60Choose it when the part is bent, formed or impact-loaded.
C63000-M10 vs C63000-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.

C63000-M10 vs C63000-O60 — frequently asked
Is C63000-M10 stronger than C63000-O60?
Yes. C63000-M10 has a typical yield strength of 380 MPa (55.1 ksi) against 310 MPa (45 ksi) for C63000-O60 — about 23% more. Tensile strength is 690 MPa (100 ksi) vs 655 MPa (95 ksi).
Which condition does FabDigit quote by default, M10 or O60?
HR50 is the default C63000 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 welds better, C63000-M10 or C63000-O60?
C63000-O60. Its weldability rates very good (70/100) against good (65/100) for C63000-M10.
