Copper Alloy C82500-M01 vs C82500-TB00
Copper Alloy · C82500 temper comparison
C82500-M01 and C82500-TB00 are two conditions of the same copper alloy grade, C82500: M01 (as sand cast) versus TB00 (solution heat treated). The chemistry is identical, so every difference below comes from the condition. C82500-M01 is the stronger of the two: yield strength 262 MPa (38 ksi) against 205 MPa (29.7 ksi) for C82500-TB00, about 28% more; tensile strength follows at 517 MPa (75 ksi) vs 480 MPa (69.6 ksi). In exchange, C82500-TB00 is the more ductile: elongation 25% versus 15% for C82500-M01, and C82500-M01 is harder (180 HB vs 115 HB). C82500-M01 conducts heat better (100 W/m·K vs 84 W/m·K). On the shop floor, C82500-M01 machines more easily (fair vs poor).
C82500-M01Choose it when strength drives the design, or when the part is machined in volume.
C82500-TB00Choose it when the part is bent, formed or impact-loaded.
C82500-M01 vs C82500-TB00: 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.

C82500-M01 vs C82500-TB00 — frequently asked
Is C82500-M01 stronger than C82500-TB00?
Yes. C82500-M01 has a typical yield strength of 262 MPa (38 ksi) against 205 MPa (29.7 ksi) for C82500-TB00 — about 28% more. Tensile strength is 517 MPa (75 ksi) vs 480 MPa (69.6 ksi).
Which condition does FabDigit quote by default, M01 or TB00?
TF00 is the default C82500 condition in the FabDigit quote flow (neither M01 nor TB00). 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 is easier to machine, C82500-M01 or C82500-TB00?
C82500-M01. Its machinability rates fair (35/100) against poor (25/100) for C82500-TB00; for welding the order is C82500-M01 first (good, 60/100) then C82500-TB00 (good, 55/100).
