Copper Alloy C82800-M vs C82800-M01
Copper Alloy · C82800 temper comparison
C82800-M and C82800-M01 are two conditions of the same copper alloy grade, C82800: M (thermomechanically controlled processed) versus M01 (as sand cast). The chemistry is identical, so every difference below comes from the condition. Both yield at about 310 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (thermomechanically controlled processed versus as sand cast). C82800-M is harder — 420 HV against 210 HV for C82800-M01 — which matters for wear surfaces and threads. C82800-M01 conducts heat better (90 W/m·K vs 78 W/m·K).

C82800-M vs C82800-M01: 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.

C82800-M vs C82800-M01 — frequently asked
What is the difference between C82800-M and C82800-M01?
C82800-M and C82800-M01 are two conditions of the same copper alloy grade, C82800: M (thermomechanically controlled processed) versus M01 (as sand cast). The chemistry is identical, so every difference below comes from the condition. Both yield at about 310 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (thermomechanically controlled processed versus as sand cast).
Which condition does FabDigit quote by default, M or M01?
TF00 is the default C82800 condition in the FabDigit quote flow (neither M nor M01). 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 is easier to machine, C82800-M or C82800-M01?
C82800-M, by a small margin. Both rate poor for machinability — 32/100 against 25/100 for C82800-M01.
