Copper Alloy C97800-M05 vs C97800-M07
Copper Alloy · C97800 temper comparison
C97800-M05 and C97800-M07 are two conditions of the same copper alloy grade, C97800: M05 (as plaster cast) versus M07 (as continuous cast). The chemistry is identical, so every difference below comes from the condition. C97800-M07 is the stronger of the two: yield strength 250 MPa (36.3 ksi) against 235 MPa (34.1 ksi) for C97800-M05, about 6% more. C97800-M07 is harder — 140 HB against 133 HB for C97800-M05 — which matters for wear surfaces and threads.
C97800-M07Choose it when strength drives the design, or when surface hardness matters.
C97800-M05 vs C97800-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.

C97800-M05 vs C97800-M07 — frequently asked
Is C97800-M07 stronger than C97800-M05?
Yes. C97800-M07 has a typical yield strength of 250 MPa (36.3 ksi) against 235 MPa (34.1 ksi) for C97800-M05 — about 6% more. Tensile strength is 435 MPa (63.1 ksi) vs 415 MPa (60.2 ksi).
Which condition does FabDigit quote by default, M05 or M07?
M01 is the default C97800 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.
When should I choose C97800-M05 over C97800-M07?
Pick C97800-M07 when strength drives the design, or when surface hardness matters.
