Copper Alloy Cu-HCP-H01 vs Cu-HCP-H80
Copper Alloy · Cu-HCP temper comparison
Cu-HCP-H01 and Cu-HCP-H80 are two conditions of the same copper alloy grade, Cu-HCP: H01 (quarter hard) versus H80 (hard drawn). The chemistry is identical, so every difference below comes from the condition. Cu-HCP-H80 is the stronger of the two: yield strength 310 MPa (45 ksi) against 195 MPa (28.3 ksi) for Cu-HCP-H01, about 59% more; tensile strength follows at 345 MPa (50 ksi) vs 260 MPa (37.7 ksi). In exchange, Cu-HCP-H01 is the more ductile: elongation 25% versus 8% for Cu-HCP-H80, and Cu-HCP-H80 is harder (90 HB vs 60 HB).
Cu-HCP-H01Choose it when the part is bent, formed or impact-loaded.
Cu-HCP-H80Choose it when strength drives the design.
Cu-HCP-H01 vs Cu-HCP-H80: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all copper alloy grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.

Cu-HCP-H01 vs Cu-HCP-H80 — frequently asked
Is Cu-HCP-H80 stronger than Cu-HCP-H01?
Yes. Cu-HCP-H80 has a typical yield strength of 310 MPa (45 ksi) against 195 MPa (28.3 ksi) for Cu-HCP-H01 — about 59% more. Tensile strength is 345 MPa (50 ksi) vs 260 MPa (37.7 ksi).
Which condition does FabDigit quote by default, H01 or H80?
O60 is the default Cu-HCP condition in the FabDigit quote flow (neither H01 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 is easier to machine, Cu-HCP-H01 or Cu-HCP-H80?
Cu-HCP-H80, by a small margin. Both rate poor for machinability — 30/100 against 25/100 for Cu-HCP-H01; for welding the order is Cu-HCP-H01 first (very good, 72/100) then Cu-HCP-H80 (good, 65/100).
