Copper Alloy C11600-H10 vs C11600-O60

Copper Alloy · C11600 temper comparison

C11600-H10 and C11600-O60 are two conditions of the same copper alloy grade, C11600: H10 (extra spring hard) versus O60 (soft annealed). The chemistry is identical, so every difference below comes from the condition. C11600-H10 is the stronger of the two: yield strength 360 MPa (52.2 ksi) against 80 MPa (11.6 ksi) for C11600-O60, about 4.5 times as much; tensile strength follows at 393 MPa (57 ksi) vs 225 MPa (32.6 ksi). In exchange, C11600-O60 is the more ductile: elongation 42% versus 3% for C11600-H10, and C11600-H10 is harder (110 HB vs 47 HB). C11600-H10 is stiffer (130 GPa vs 115 GPa) and C11600-O60 runs hotter in service (300°C vs 250°C continuous).

C11600-H10Choose it when strength drives the design.

C11600-O60Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

C11600-H10 vs C11600-O60 — frequently asked

Is C11600-H10 stronger than C11600-O60?

Yes. C11600-H10 has a typical yield strength of 360 MPa (52.2 ksi) against 80 MPa (11.6 ksi) for C11600-O60 — about 4.5 times as much. Tensile strength is 393 MPa (57 ksi) vs 225 MPa (32.6 ksi).

Which condition does FabDigit quote by default, H10 or O60?

H02 is the default C11600 condition in the FabDigit quote flow (neither H10 nor O60). 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.

Which is easier to machine, C11600-H10 or C11600-O60?

C11600-H10, by a small margin. Both rate poor for machinability — 25/100 against 20/100 for C11600-O60.
