Copper Alloy C80900-M01 vs C80900-M02
Copper Alloy · C80900 temper comparison
C80900-M01 and C80900-M02 are two conditions of the same copper alloy grade, C80900: M01 (as sand cast) versus M02 (as centrifugally cast). The chemistry is identical, so every difference below comes from the condition. C80900-M02 is the stronger of the two: yield strength 70 MPa (10.2 ksi) against 62 MPa (8.99 ksi) for C80900-M01, about 13% more; tensile strength follows at 190 MPa (27.6 ksi) vs 172 MPa (24.9 ksi). In exchange, C80900-M01 is the more ductile: elongation 40% versus 35% for C80900-M02, and C80900-M02 is harder (48 HB vs 44 HB).
C80900-M01Choose it when the part is bent, formed or impact-loaded.
C80900-M02Choose it when strength drives the design.
C80900-M01 vs C80900-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.

C80900-M01 vs C80900-M02 — frequently asked
Is C80900-M02 stronger than C80900-M01?
Yes. C80900-M02 has a typical yield strength of 70 MPa (10.2 ksi) against 62 MPa (8.99 ksi) for C80900-M01 — about 13% more. Tensile strength is 190 MPa (27.6 ksi) vs 172 MPa (24.9 ksi).
Which condition does FabDigit quote by default, M01 or M02?
M01 is the default C80900 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 C80900-M01 over C80900-M02?
Pick C80900-M01 when the part is bent, formed or impact-loaded. Pick C80900-M02 when strength drives the design.
