Copper Alloy C91300-M01 vs C91300-M02
Copper Alloy · C91300 temper comparison
C91300-M01 and C91300-M02 are two conditions of the same copper alloy grade, C91300: M01 (as sand cast) versus M02 (as centrifugally cast). The chemistry is identical, so every difference below comes from the condition. C91300-M02 is the stronger of the two: yield strength 240 MPa (34.8 ksi) against 210 MPa (30.5 ksi) for C91300-M01, about 14% more; tensile strength follows at 270 MPa (39.2 ksi) vs 240 MPa (34.8 ksi). C91300-M02 is harder — 24 HRC against 22 HRC for C91300-M01 — which matters for wear surfaces and threads.
C91300-M02Choose it when strength drives the design, or when surface hardness matters.
C91300-M01 vs C91300-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.

C91300-M01 vs C91300-M02 — frequently asked
Is C91300-M02 stronger than C91300-M01?
Yes. C91300-M02 has a typical yield strength of 240 MPa (34.8 ksi) against 210 MPa (30.5 ksi) for C91300-M01 — about 14% more. Tensile strength is 270 MPa (39.2 ksi) vs 240 MPa (34.8 ksi).
Which condition does FabDigit quote by default, M01 or M02?
M01 is the default C91300 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 C91300-M01 over C91300-M02?
Pick C91300-M02 when strength drives the design, or when surface hardness matters.
