Copper Alloy C96900-M01 vs C96900-M02
Copper Alloy · C96900 temper comparison
C96900-M01 and C96900-M02 are two conditions of the same copper alloy grade, C96900: M01 (as sand cast) versus M02 (as centrifugally cast). The chemistry is identical, so every difference below comes from the condition. C96900-M02 is the stronger of the two: yield strength 260 MPa (37.7 ksi) against 240 MPa (34.8 ksi) for C96900-M01, about 8% more; tensile strength follows at 520 MPa (75.4 ksi) vs 480 MPa (69.6 ksi). C96900-M02 is the more ductile: elongation 15% versus 12% for C96900-M01, and C96900-M02 is harder (170 HB vs 160 HB). On the shop floor, C96900-M02 welds better (fair vs poor).
C96900-M02Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
C96900-M01 vs C96900-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.

C96900-M01 vs C96900-M02 — frequently asked
Is C96900-M02 stronger than C96900-M01?
Yes. C96900-M02 has a typical yield strength of 260 MPa (37.7 ksi) against 240 MPa (34.8 ksi) for C96900-M01 — about 8% more. Tensile strength is 520 MPa (75.4 ksi) vs 480 MPa (69.6 ksi).
Which condition does FabDigit quote by default, M01 or M02?
TX00 is the default C96900 condition in the FabDigit quote flow (neither M01 nor M02). 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 welds better, C96900-M01 or C96900-M02?
C96900-M02. Its weldability rates fair (45/100) against poor (25/100) for C96900-M01.
