Copper Alloy Cu-FRHC-H06 vs Cu-FRHC-H10

Copper Alloy · Cu-FRHC temper comparison

Cu-FRHC-H06 and Cu-FRHC-H10 are two conditions of the same copper alloy grade, Cu-FRHC: H06 (extra hard) versus H10 (extra spring hard). The chemistry is identical, so every difference below comes from the condition. Cu-FRHC-H10 is the stronger of the two: yield strength 365 MPa (52.9 ksi) against 330 MPa (47.9 ksi) for Cu-FRHC-H06, about 11% more; tensile strength follows at 395 MPa (57.3 ksi) vs 365 MPa (52.9 ksi). In exchange, Cu-FRHC-H06 is the more ductile: elongation 5% versus 4% for Cu-FRHC-H10, and Cu-FRHC-H10 is harder (105 HB vs 97 HB).

Cu-FRHC-H06Choose it when the part is bent, formed or impact-loaded.

Cu-FRHC-H10Choose it when strength drives the design.

Cu-FRHC-H06 vs Cu-FRHC-H10 — frequently asked

Is Cu-FRHC-H10 stronger than Cu-FRHC-H06?

Yes. Cu-FRHC-H10 has a typical yield strength of 365 MPa (52.9 ksi) against 330 MPa (47.9 ksi) for Cu-FRHC-H06 — about 11% more. Tensile strength is 395 MPa (57.3 ksi) vs 365 MPa (52.9 ksi).

Which condition does FabDigit quote by default, H06 or H10?

O60 is the default Cu-FRHC condition in the FabDigit quote flow (neither H06 nor H10). 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.

When should I choose Cu-FRHC-H06 over Cu-FRHC-H10?

Pick Cu-FRHC-H06 when the part is bent, formed or impact-loaded. Pick Cu-FRHC-H10 when strength drives the design.
