Copper Alloy C82800-M vs C82800-TF00

Copper Alloy · C82800 temper comparison

C82800-M and C82800-TF00 are two conditions of the same copper alloy grade, C82800: M (thermomechanically controlled processed) versus TF00 (solution heat treated and precipitation hardened). The chemistry is identical, so every difference below comes from the condition. C82800-TF00 is the stronger of the two: yield strength 1,000 MPa (145 ksi) against 310 MPa (45 ksi) for C82800-M, about 3.2 times as much; tensile strength follows at 1,069 MPa (155 ksi) vs 552 MPa (80.1 ksi). In exchange, C82800-M is the more ductile: elongation 1% versus 0.5% for C82800-TF00, and C82800-TF00 is harder (400 HB vs 200 HB). C82800-TF00 conducts heat better (105 W/m·K vs 78 W/m·K).

C82800-MChoose it when the part is bent, formed or impact-loaded.

C82800-TF00Choose it when strength drives the design.

C82800-M vs C82800-TF00 — frequently asked

Is C82800-TF00 stronger than C82800-M?

Yes. C82800-TF00 has a typical yield strength of 1,000 MPa (145 ksi) against 310 MPa (45 ksi) for C82800-M — about 3.2 times as much. Tensile strength is 1,069 MPa (155 ksi) vs 552 MPa (80.1 ksi).

Which condition does FabDigit quote by default, M or TF00?

TF00 is the default C82800 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 C82800-M over C82800-TF00?

Pick C82800-M when the part is bent, formed or impact-loaded. Pick C82800-TF00 when strength drives the design.
