Copper Alloy C82800-M01 vs C82800-TB00
Copper Alloy · C82800 temper comparison
C82800-M01 and C82800-TB00 are two conditions of the same copper alloy grade, C82800: M01 (as sand cast) versus TB00 (solution heat treated). The chemistry is identical, so every difference below comes from the condition. C82800-M01 is the stronger of the two: yield strength 310 MPa (45 ksi) against 240 MPa (34.8 ksi) for C82800-TB00, about 29% more; tensile strength follows at 552 MPa (80.1 ksi) vs 520 MPa (75.4 ksi). In exchange, C82800-TB00 is the more ductile: elongation 12% versus 1% for C82800-M01, and C82800-M01 is harder (200 HB vs 155 HB). C82800-M01 runs hotter in service (200°C vs 150°C continuous) and C82800-M01 conducts heat better (90 W/m·K vs 62 W/m·K).
C82800-M01Choose it when strength drives the design, or when the part sees heat.
C82800-TB00Choose it when the part is bent, formed or impact-loaded.
C82800-M01 vs C82800-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.

C82800-M01 vs C82800-TB00 — frequently asked
Is C82800-M01 stronger than C82800-TB00?
Yes. C82800-M01 has a typical yield strength of 310 MPa (45 ksi) against 240 MPa (34.8 ksi) for C82800-TB00 — about 29% more. Tensile strength is 552 MPa (80.1 ksi) vs 520 MPa (75.4 ksi).
Which condition does FabDigit quote by default, M01 or TB00?
TF00 is the default C82800 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.
When should I choose C82800-M01 over C82800-TB00?
Pick C82800-M01 when strength drives the design, or when the part sees heat. Pick C82800-TB00 when the part is bent, formed or impact-loaded.
