Copper Alloy C87500-M02 vs C87500-M06
Copper Alloy · C87500 temper comparison
C87500-M02 and C87500-M06 are two conditions of the same copper alloy grade, C87500: M02 (as centrifugally cast) versus M06 (as investment cast). The chemistry is identical, so every difference below comes from the condition. Both yield at about 240 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (as centrifugally cast versus as investment cast). C87500-M06 is the more ductile: elongation 21% versus 18% for C87500-M02.

C87500-M02 vs C87500-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.

C87500-M02 vs C87500-M06 — frequently asked
What is the difference between C87500-M02 and C87500-M06?
C87500-M02 and C87500-M06 are two conditions of the same copper alloy grade, C87500: M02 (as centrifugally cast) versus M06 (as investment cast). The chemistry is identical, so every difference below comes from the condition. Both yield at about 240 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (as centrifugally cast versus as investment cast).
Which condition does FabDigit quote by default, M02 or M06?
M01 is the default C87500 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.
Which welds better, C87500-M02 or C87500-M06?
C87500-M02. Its weldability rates good (65/100) against good (60/100) for C87500-M06.
