Copper Alloy Cu-FRTP-H02 vs Cu-FRTP-O60

Copper Alloy · Cu-FRTP temper comparison

Cu-FRTP-H02 and Cu-FRTP-O60 are two conditions of the same copper alloy grade, Cu-FRTP: H02 (half hard) versus O60 (soft annealed). The chemistry is identical, so every difference below comes from the condition. Cu-FRTP-H02 is the stronger of the two: yield strength 250 MPa (36.3 ksi) against 70 MPa (10.2 ksi) for Cu-FRTP-O60, about 3.6 times as much; tensile strength follows at 300 MPa (43.5 ksi) vs 225 MPa (32.6 ksi). In exchange, Cu-FRTP-O60 is the more ductile: elongation 45% versus 14% for Cu-FRTP-H02, and Cu-FRTP-H02 is harder (85 HB vs 45 HB). Cu-FRTP-O60 runs hotter in service (200°C vs 150°C continuous).

Cu-FRTP-H02Choose it when strength drives the design.

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

Cu-FRTP-H02 vs Cu-FRTP-O60 — frequently asked

Is Cu-FRTP-H02 stronger than Cu-FRTP-O60?

Yes. Cu-FRTP-H02 has a typical yield strength of 250 MPa (36.3 ksi) against 70 MPa (10.2 ksi) for Cu-FRTP-O60 — about 3.6 times as much. Tensile strength is 300 MPa (43.5 ksi) vs 225 MPa (32.6 ksi).

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

H04 is the default Cu-FRTP 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, Cu-FRTP-H02 or Cu-FRTP-O60?

Cu-FRTP-H02, by a small margin. Both rate poor for machinability — 26/100 against 20/100 for Cu-FRTP-O60.
