Copper Alloy C80500-M02 vs C80500-M06
Copper Alloy · C80500 temper comparison
C80500-M02 and C80500-M06 are two conditions of the same copper alloy grade, C80500: M02 (as centrifugally cast) versus M06 (as investment cast). The chemistry is identical, so every difference below comes from the condition. C80500-M02 is the stronger of the two: yield strength 70 MPa (10.2 ksi) against 65 MPa (9.43 ksi) for C80500-M06, about 8% more; tensile strength follows at 195 MPa (28.3 ksi) vs 180 MPa (26.1 ksi). C80500-M02 is harder — 48 HB against 45 HB for C80500-M06 — which matters for wear surfaces and threads.
C80500-M02Choose it when strength drives the design, or when surface hardness matters.
C80500-M02 vs C80500-M06: 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.

C80500-M02 vs C80500-M06 — frequently asked
Is C80500-M02 stronger than C80500-M06?
Yes. C80500-M02 has a typical yield strength of 70 MPa (10.2 ksi) against 65 MPa (9.43 ksi) for C80500-M06 — about 8% more. Tensile strength is 195 MPa (28.3 ksi) vs 180 MPa (26.1 ksi).
Which condition does FabDigit quote by default, M02 or M06?
M01 is the default C80500 condition in the FabDigit quote flow (neither M02 nor M06). 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.
When should I choose C80500-M02 over C80500-M06?
Pick C80500-M02 when strength drives the design, or when surface hardness matters.
