Copper Alloy C14520-H01 vs C14520-H06
Copper Alloy · C14520 temper comparison
C14520-H01 and C14520-H06 are two conditions of the same copper alloy grade, C14520: H01 (quarter hard) versus H06 (extra hard). The chemistry is identical, so every difference below comes from the condition. C14520-H06 is the stronger of the two: yield strength 340 MPa (49.3 ksi) against 215 MPa (31.2 ksi) for C14520-H01, about 58% more; tensile strength follows at 365 MPa (52.9 ksi) vs 275 MPa (39.9 ksi). In exchange, C14520-H01 is the more ductile: elongation 25% versus 7% for C14520-H06, and C14520-H06 is harder (110 HB vs 80 HB). C14520-H01 runs hotter in service (200°C vs 175°C continuous).
C14520-H01Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C14520-H06Choose it when strength drives the design.
C14520-H01 vs C14520-H06: 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.

C14520-H01 vs C14520-H06 — frequently asked
Is C14520-H06 stronger than C14520-H01?
Yes. C14520-H06 has a typical yield strength of 340 MPa (49.3 ksi) against 215 MPa (31.2 ksi) for C14520-H01 — about 58% more. Tensile strength is 365 MPa (52.9 ksi) vs 275 MPa (39.9 ksi).
Which condition does FabDigit quote by default, H01 or H06?
H04 is the default C14520 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, C14520-H01 or C14520-H06?
C14520-H06. Its machinability rates excellent (88/100) against very good (82/100) for C14520-H01; for welding the order is C14520-H01 first (good, 55/100) then C14520-H06 (fair, 50/100).
