Copper Alloy C82100-M02 vs C82100-TB00
Copper Alloy · C82100 temper comparison
C82100-M02 and C82100-TB00 are two conditions of the same copper alloy grade, C82100: M02 (as centrifugally cast) versus TB00 (solution heat treated). The chemistry is identical, so every difference below comes from the condition. C82100-M02 is the stronger of the two: yield strength 185 MPa (26.8 ksi) against 140 MPa (20.3 ksi) for C82100-TB00, about 32% more; tensile strength follows at 345 MPa (50 ksi) vs 310 MPa (45 ksi). In exchange, C82100-TB00 is the more ductile: elongation 25% versus 20% for C82100-M02, and C82100-M02 is harder (90 HB vs 80 HB). C82100-M02 runs hotter in service (200°C vs 150°C continuous) and C82100-M02 conducts heat better (105 W/m·K vs 90 W/m·K).
C82100-M02Choose it when strength drives the design, or when the part sees heat.
C82100-TB00Choose it when the part is bent, formed or impact-loaded.
C82100-M02 vs C82100-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.

C82100-M02 vs C82100-TB00 — frequently asked
Is C82100-M02 stronger than C82100-TB00?
Yes. C82100-M02 has a typical yield strength of 185 MPa (26.8 ksi) against 140 MPa (20.3 ksi) for C82100-TB00 — about 32% more. Tensile strength is 345 MPa (50 ksi) vs 310 MPa (45 ksi).
Which condition does FabDigit quote by default, M02 or TB00?
TF00 is the default C82100 condition in the FabDigit quote flow (neither M02 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.
When should I choose C82100-M02 over C82100-TB00?
Pick C82100-M02 when strength drives the design, or when the part sees heat. Pick C82100-TB00 when the part is bent, formed or impact-loaded.
