Copper Alloy Cu-FRHC-H01 vs Cu-FRHC-H06

Copper Alloy · Cu-FRHC temper comparison

Cu-FRHC-H01 and Cu-FRHC-H06 are two conditions of the same copper alloy grade, Cu-FRHC: H01 (quarter hard) versus H06 (extra hard). The chemistry is identical, so every difference below comes from the condition. Cu-FRHC-H06 is the stronger of the two: yield strength 330 MPa (47.9 ksi) against 210 MPa (30.5 ksi) for Cu-FRHC-H01, about 57% more; tensile strength follows at 365 MPa (52.9 ksi) vs 265 MPa (38.4 ksi). In exchange, Cu-FRHC-H01 is the more ductile: elongation 25% versus 5% for Cu-FRHC-H06, and Cu-FRHC-H06 is harder (97 HB vs 68 HB). Cu-FRHC-H01 runs hotter in service (200°C vs 150°C continuous).

Cu-FRHC-H01Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

Cu-FRHC-H06Choose it when strength drives the design.

Cu-FRHC-H01 vs Cu-FRHC-H06 — frequently asked

Is Cu-FRHC-H06 stronger than Cu-FRHC-H01?

Yes. Cu-FRHC-H06 has a typical yield strength of 330 MPa (47.9 ksi) against 210 MPa (30.5 ksi) for Cu-FRHC-H01 — about 57% more. Tensile strength is 365 MPa (52.9 ksi) vs 265 MPa (38.4 ksi).

Which condition does FabDigit quote by default, H01 or H06?

O60 is the default Cu-FRHC condition in the FabDigit quote flow (neither H01 nor H06). 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-FRHC-H01 or Cu-FRHC-H06?

Cu-FRHC-H06, by a small margin. Both rate poor for machinability — 32/100 against 24/100 for Cu-FRHC-H01.
