Copper Alloy C15760-H02 vs C15760-H08

Copper Alloy · C15760 temper comparison

C15760-H02 and C15760-H08 are two conditions of the same copper alloy grade, C15760: H02 (half hard) versus H08 (spring hard). The chemistry is identical, so every difference below comes from the condition. C15760-H08 is the stronger of the two: yield strength 615 MPa (89.2 ksi) against 490 MPa (71.1 ksi) for C15760-H02, about 26% more; tensile strength follows at 655 MPa (95 ksi) vs 555 MPa (80.5 ksi). In exchange, C15760-H02 is the more ductile: elongation 14% versus 8% for C15760-H08, and C15760-H08 is harder (178 HB vs 152 HB).

C15760-H02Choose it when the part is bent, formed or impact-loaded.

C15760-H08Choose it when strength drives the design.

C15760-H02 vs C15760-H08 — frequently asked

Is C15760-H08 stronger than C15760-H02?

Yes. C15760-H08 has a typical yield strength of 615 MPa (89.2 ksi) against 490 MPa (71.1 ksi) for C15760-H02 — about 26% more. Tensile strength is 655 MPa (95 ksi) vs 555 MPa (80.5 ksi).

Which condition does FabDigit quote by default, H02 or H08?

H04 is the default C15760 condition in the FabDigit quote flow (neither H02 nor H08). 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 C15760-H02 over C15760-H08?

Pick C15760-H02 when the part is bent, formed or impact-loaded. Pick C15760-H08 when strength drives the design.
