Copper Alloy C86500-M05 vs C86500-M07
Copper Alloy · C86500 temper comparison
C86500-M05 and C86500-M07 are two conditions of the same copper alloy grade, C86500: M05 (as plaster cast) versus M07 (as continuous cast). The chemistry is identical, so every difference below comes from the condition. Both yield at about 215 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (as plaster cast versus as continuous cast). For most parts the choice follows the drawing's specified condition; ask for the one your standard calls out.
C86500-M05 vs C86500-M07: 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.

C86500-M05 vs C86500-M07 — frequently asked
What is the difference between C86500-M05 and C86500-M07?
C86500-M05 and C86500-M07 are two conditions of the same copper alloy grade, C86500: M05 (as plaster cast) versus M07 (as continuous cast). The chemistry is identical, so every difference below comes from the condition. Both yield at about 215 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (as plaster cast versus as continuous cast).
Which condition does FabDigit quote by default, M05 or M07?
M01 is the default C86500 condition in the FabDigit quote flow (neither M05 nor M07). 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.
