Copper Alloy C67000-H02 vs C67000-O60

Copper Alloy · C67000 temper comparison

C67000-H02 and C67000-O60 are two conditions of the same copper alloy grade, C67000: H02 (half hard) versus O60 (soft annealed). The chemistry is identical, so every difference below comes from the condition. C67000-H02 is the stronger of the two: yield strength 379 MPa (55 ksi) against 290 MPa (42.1 ksi) for C67000-O60, about 31% more; tensile strength follows at 655 MPa (95 ksi) vs 565 MPa (81.9 ksi). In exchange, C67000-O60 is the more ductile: elongation 32% versus 20% for C67000-H02, and C67000-H02 is harder (185 HB vs 140 HB). C67000-O60 runs hotter in service (250°C vs 200°C continuous).

C67000-H02 vs C67000-O60 — frequently asked

Is C67000-H02 stronger than C67000-O60?

Yes. C67000-H02 has a typical yield strength of 379 MPa (55 ksi) against 290 MPa (42.1 ksi) for C67000-O60 — about 31% more. Tensile strength is 655 MPa (95 ksi) vs 565 MPa (81.9 ksi).

Which condition does FabDigit quote by default, H02 or O60?

H02 is the default C67000 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.

Which is easier to machine, C67000-H02 or C67000-O60?

C67000-H02, by a small margin. Both rate poor for machinability — 32/100 against 25/100 for C67000-O60.
