Copper Alloy C15760-H01 vs C15760-H08

Copper Alloy · C15760 temper comparison

C15760-H01 and C15760-H08 are two conditions of the same copper alloy grade, C15760: H01 (quarter 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 440 MPa (63.8 ksi) for C15760-H01, about 40% more; tensile strength follows at 655 MPa (95 ksi) vs 525 MPa (76.1 ksi). In exchange, C15760-H01 is the more ductile: elongation 16% versus 8% for C15760-H08, and C15760-H08 is harder (178 HB vs 140 HB).

C15760-H01Choose it when the part is bent, formed or impact-loaded.

C15760-H08Choose it when strength drives the design.

C15760-H01 vs C15760-H08 — frequently asked

Is C15760-H08 stronger than C15760-H01?

Yes. C15760-H08 has a typical yield strength of 615 MPa (89.2 ksi) against 440 MPa (63.8 ksi) for C15760-H01 — about 40% more. Tensile strength is 655 MPa (95 ksi) vs 525 MPa (76.1 ksi).

Which condition does FabDigit quote by default, H01 or H08?

H04 is the default C15760 condition in the FabDigit quote flow (neither H01 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-H01 over C15760-H08?

Pick C15760-H01 when the part is bent, formed or impact-loaded. Pick C15760-H08 when strength drives the design.
