Copper Alloy C19020-H02 vs C19020-O60

Copper Alloy · C19020 temper comparison

C19020-H02 and C19020-O60 are two conditions of the same copper alloy grade, C19020: H02 (half hard) versus O60 (soft annealed). The chemistry is identical, so every difference below comes from the condition. C19020-H02 is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 140 MPa (20.3 ksi) for C19020-O60, about 171% more; tensile strength follows at 425 MPa (61.6 ksi) vs 320 MPa (46.4 ksi). In exchange, C19020-O60 is the more ductile: elongation 32% versus 12% for C19020-H02, and C19020-O60 is harder (152 HB vs 123 HB). C19020-O60 runs hotter in service (200°C vs 120°C continuous).

C19020-H02Choose it when strength drives the design.

C19020-O60Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

C19020-H02 vs C19020-O60 — frequently asked

Is C19020-H02 stronger than C19020-O60?

Yes. C19020-H02 has a typical yield strength of 380 MPa (55.1 ksi) against 140 MPa (20.3 ksi) for C19020-O60 — about 171% more. Tensile strength is 425 MPa (61.6 ksi) vs 320 MPa (46.4 ksi).

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

HR04 is the default C19020 condition in the FabDigit quote flow (neither H02 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, C19020-H02 or C19020-O60?

C19020-H02, by a small margin. Both rate poor for machinability — 30/100 against 22/100 for C19020-O60.
