Copper Alloy C73200-H02 vs C73200-H06
Copper Alloy · C73200 temper comparison
C73200-H02 and C73200-H06 are two conditions of the same copper alloy grade, C73200: H02 (half hard) versus H06 (extra hard). The chemistry is identical, so every difference below comes from the condition. C73200-H06 is the stronger of the two: yield strength 510 MPa (74 ksi) against 380 MPa (55.1 ksi) for C73200-H02, about 34% more; tensile strength follows at 590 MPa (85.6 ksi) vs 470 MPa (68.2 ksi). In exchange, C73200-H02 is the more ductile: elongation 12% versus 3% for C73200-H06, and C73200-H06 is harder (175 HB vs 130 HB). C73200-H02 runs hotter in service (200°C vs 150°C continuous).
C73200-H02Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C73200-H06Choose it when strength drives the design.
C73200-H02 vs C73200-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.

C73200-H02 vs C73200-H06 — frequently asked
Is C73200-H06 stronger than C73200-H02?
Yes. C73200-H06 has a typical yield strength of 510 MPa (74 ksi) against 380 MPa (55.1 ksi) for C73200-H02 — about 34% more. Tensile strength is 590 MPa (85.6 ksi) vs 470 MPa (68.2 ksi).
Which condition does FabDigit quote by default, H02 or H06?
H02 is the default C73200 condition in the FabDigit quote flow. 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, C73200-H02 or C73200-H06?
C73200-H06, by a small margin. Both rate poor for machinability — 32/100 against 25/100 for C73200-H02; for welding the order is C73200-H02 first (good, 55/100) then C73200-H06 (fair, 48/100).
