Copper Alloy C97300-M01 vs C97300-M02
Copper Alloy · C97300 temper comparison
C97300-M01 and C97300-M02 are two conditions of the same copper alloy grade, C97300: M01 (as sand cast) versus M02 (as centrifugally cast). The chemistry is identical, so every difference below comes from the condition. C97300-M02 is the stronger of the two: yield strength 125 MPa (18.1 ksi) against 117 MPa (17 ksi) for C97300-M01, about 7% more. In exchange, C97300-M01 is the more ductile: elongation 18% versus 16% for C97300-M02, and C97300-M02 is harder (58 HB vs 55 HB).
C97300-M01Choose it when the part is bent, formed or impact-loaded.
C97300-M02Choose it when strength drives the design.
C97300-M01 vs C97300-M02: 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.

C97300-M01 vs C97300-M02 — frequently asked
Is C97300-M02 stronger than C97300-M01?
Yes. C97300-M02 has a typical yield strength of 125 MPa (18.1 ksi) against 117 MPa (17 ksi) for C97300-M01 — about 7% more. Tensile strength is 250 MPa (36.3 ksi) vs 240 MPa (34.8 ksi).
Which condition does FabDigit quote by default, M01 or M02?
M01 is the default C97300 condition in the FabDigit quote flow. 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 C97300-M01 over C97300-M02?
Pick C97300-M01 when the part is bent, formed or impact-loaded. Pick C97300-M02 when strength drives the design.
