Copper Alloy C62500-M10 vs C62500-O60
Copper Alloy · C62500 temper comparison
C62500-M10 and C62500-O60 are two conditions of the same copper alloy grade, C62500: M10 (as hot forged and air cooled) versus O60 (soft annealed). The chemistry is identical, so every difference below comes from the condition. C62500-M10 is the stronger of the two: yield strength 400 MPa (58 ksi) against 340 MPa (49.3 ksi) for C62500-O60, about 18% more; tensile strength follows at 740 MPa (107 ksi) vs 620 MPa (89.9 ksi). C62500-M10 is harder — 230 HB against 195 HB for C62500-O60 — which matters for wear surfaces and threads.
C62500-M10Choose it when strength drives the design, or when surface hardness matters.
C62500-M10 vs C62500-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.

C62500-M10 vs C62500-O60 — frequently asked
Is C62500-M10 stronger than C62500-O60?
Yes. C62500-M10 has a typical yield strength of 400 MPa (58 ksi) against 340 MPa (49.3 ksi) for C62500-O60 — about 18% more. Tensile strength is 740 MPa (107 ksi) vs 620 MPa (89.9 ksi).
Which condition does FabDigit quote by default, M10 or O60?
M30 is the default C62500 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, C62500-M10 or C62500-O60?
C62500-O60. Its weldability rates poor (30/100) against poor (25/100) for C62500-M10.
