Copper Alloy C18200-TF00 vs C18200-TH02

Copper Alloy · C18200 temper comparison

C18200-TF00 and C18200-TH02 are two conditions of the same copper alloy grade, C18200: TF00 (solution heat treated and precipitation hardened) versus TH02 (TD02 and precipitation hardened). The chemistry is identical, so every difference below comes from the condition. C18200-TH02 is the stronger of the two: yield strength 427 MPa (61.9 ksi) against 372 MPa (54 ksi) for C18200-TF00, about 15% more; tensile strength follows at 496 MPa (71.9 ksi) vs 448 MPa (65 ksi). In exchange, C18200-TF00 is the more ductile: elongation 22% versus 18% for C18200-TH02, and C18200-TH02 is harder (140 HB vs 120 HB).

C18200-TF00Choose it when the part is bent, formed or impact-loaded.

C18200-TH02Choose it when strength drives the design.

C18200-TF00 vs C18200-TH02 — frequently asked

Is C18200-TH02 stronger than C18200-TF00?

Yes. C18200-TH02 has a typical yield strength of 427 MPa (61.9 ksi) against 372 MPa (54 ksi) for C18200-TF00 — about 15% more. Tensile strength is 496 MPa (71.9 ksi) vs 448 MPa (65 ksi).

Which condition does FabDigit quote by default, TF00 or TH02?

H is the default C18200 condition in the FabDigit quote flow (neither TF00 nor TH02). 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 C18200-TF00 over C18200-TH02?

Pick C18200-TF00 when the part is bent, formed or impact-loaded. Pick C18200-TH02 when strength drives the design.
