Copper Alloy C33000-H02 vs C33000-H80

Copper Alloy · C33000 temper comparison

C33000-H02 and C33000-H80 are two conditions of the same copper alloy grade, C33000: H02 (half hard) versus H80 (hard drawn). The chemistry is identical, so every difference below comes from the condition. C33000-H80 is the stronger of the two: yield strength 415 MPa (60.2 ksi) against 275 MPa (39.9 ksi) for C33000-H02, about 51% more; tensile strength follows at 520 MPa (75.4 ksi) vs 420 MPa (60.9 ksi). In exchange, C33000-H02 is the more ductile: elongation 25% versus 6% for C33000-H80, and C33000-H80 is harder (155 HB vs 110 HB).

C33000-H02Choose it when the part is bent, formed or impact-loaded.

C33000-H80Choose it when strength drives the design.

C33000-H02 vs C33000-H80 — frequently asked

Is C33000-H80 stronger than C33000-H02?

Yes. C33000-H80 has a typical yield strength of 415 MPa (60.2 ksi) against 275 MPa (39.9 ksi) for C33000-H02 — about 51% more. Tensile strength is 520 MPa (75.4 ksi) vs 420 MPa (60.9 ksi).

Which condition does FabDigit quote by default, H02 or H80?

O is the default C33000 condition in the FabDigit quote flow (neither H02 nor H80). 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 C33000-H02 over C33000-H80?

Pick C33000-H02 when the part is bent, formed or impact-loaded. Pick C33000-H80 when strength drives the design.
