Copper Alloy Cu-HCP-H10 vs Cu-HCP-H80

Copper Alloy · Cu-HCP temper comparison

Cu-HCP-H10 and Cu-HCP-H80 are two conditions of the same copper alloy grade, Cu-HCP: H10 (extra spring hard) versus H80 (hard drawn). The chemistry is identical, so every difference below comes from the condition. Cu-HCP-H10 is the stronger of the two: yield strength 370 MPa (53.7 ksi) against 310 MPa (45 ksi) for Cu-HCP-H80, about 19% more; tensile strength follows at 400 MPa (58 ksi) vs 345 MPa (50 ksi). In exchange, Cu-HCP-H80 is the more ductile: elongation 8% versus 3% for Cu-HCP-H10, and Cu-HCP-H10 is harder (105 HB vs 90 HB). Cu-HCP-H80 runs hotter in service (150°C vs 120°C continuous). On the shop floor, Cu-HCP-H80 welds better (65 vs 55 out of 100).

Cu-HCP-H10 vs Cu-HCP-H80 — frequently asked

Is Cu-HCP-H10 stronger than Cu-HCP-H80?

Yes. Cu-HCP-H10 has a typical yield strength of 370 MPa (53.7 ksi) against 310 MPa (45 ksi) for Cu-HCP-H80 — about 19% more. Tensile strength is 400 MPa (58 ksi) vs 345 MPa (50 ksi).

Which condition does FabDigit quote by default, H10 or H80?

O60 is the default Cu-HCP condition in the FabDigit quote flow (neither H10 nor H80). 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 welds better, Cu-HCP-H10 or Cu-HCP-H80?

Cu-HCP-H80. Its weldability rates good (65/100) against good (55/100) for Cu-HCP-H10.
