Copper Alloy C36000-H02 vs C36000-H04

Copper Alloy · C36000 temper comparison

C36000-H02 and C36000-H04 are two conditions of the same copper alloy grade, C36000: H02 (half hard) versus H04 (full hard). The chemistry is identical, so every difference below comes from the condition. C36000-H04 is the stronger of the two: yield strength 400 MPa (58 ksi) against 310 MPa (45 ksi) for C36000-H02, about 29% more; tensile strength follows at 470 MPa (68.2 ksi) vs 385 MPa (55.8 ksi). In exchange, C36000-H02 is the more ductile: elongation 22% versus 12% for C36000-H04, and C36000-H04 is harder (140 HB vs 115 HB). C36000-H02 runs hotter in service (200°C vs 180°C continuous).

C36000-H02Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

C36000-H04Choose it when strength drives the design.

C36000-H02 vs C36000-H04 — frequently asked

Is C36000-H04 stronger than C36000-H02?

Yes. C36000-H04 has a typical yield strength of 400 MPa (58 ksi) against 310 MPa (45 ksi) for C36000-H02 — about 29% more. Tensile strength is 470 MPa (68.2 ksi) vs 385 MPa (55.8 ksi).

Which condition does FabDigit quote by default, H02 or H04?

H02 is the default C36000 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 C36000-H02 over C36000-H04?

Pick C36000-H02 when the part is bent, formed or impact-loaded, or when the part sees heat. Pick C36000-H04 when strength drives the design.
