Copper Alloy C79600-H01 vs C79600-H04

Copper Alloy · C79600 temper comparison

C79600-H01 and C79600-H04 are two conditions of the same copper alloy grade, C79600: H01 (quarter hard) versus H04 (full hard). The chemistry is identical, so every difference below comes from the condition. C79600-H04 is the stronger of the two: yield strength 480 MPa (69.6 ksi) against 310 MPa (45 ksi) for C79600-H01, about 55% more; tensile strength follows at 620 MPa (89.9 ksi) vs 480 MPa (69.6 ksi). In exchange, C79600-H01 is the more ductile: elongation 22% versus 8% for C79600-H04, and C79600-H04 is harder (185 HB vs 140 HB). C79600-H01 runs hotter in service (180°C vs 150°C continuous).

C79600-H01Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

C79600-H04Choose it when strength drives the design.

C79600-H01 vs C79600-H04 — frequently asked

Is C79600-H04 stronger than C79600-H01?

Yes. C79600-H04 has a typical yield strength of 480 MPa (69.6 ksi) against 310 MPa (45 ksi) for C79600-H01 — about 55% more. Tensile strength is 620 MPa (89.9 ksi) vs 480 MPa (69.6 ksi).

Which condition does FabDigit quote by default, H01 or H04?

H02 is the default C79600 condition in the FabDigit quote flow (neither H01 nor H04). 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 C79600-H01 over C79600-H04?

Pick C79600-H01 when the part is bent, formed or impact-loaded, or when the part sees heat. Pick C79600-H04 when strength drives the design.
