Copper Alloy C18600-H02 vs C18600-TB00
Copper Alloy · C18600 temper comparison
C18600-H02 and C18600-TB00 are two conditions of the same copper alloy grade, C18600: H02 (half hard) versus TB00 (solution heat treated). The chemistry is identical, so every difference below comes from the condition. C18600-H02 is the stronger of the two: yield strength 300 MPa (43.5 ksi) against 95 MPa (13.8 ksi) for C18600-TB00, about 3.2 times as much; tensile strength follows at 360 MPa (52.2 ksi) vs 250 MPa (36.3 ksi). In exchange, C18600-TB00 is the more ductile: elongation 40% versus 12% for C18600-H02, and C18600-H02 is harder (105 HB vs 60 HB).
C18600-H02Choose it when strength drives the design.
C18600-TB00Choose it when the part is bent, formed or impact-loaded.
C18600-H02 vs C18600-TB00: 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.

C18600-H02 vs C18600-TB00 — frequently asked
Is C18600-H02 stronger than C18600-TB00?
Yes. C18600-H02 has a typical yield strength of 300 MPa (43.5 ksi) against 95 MPa (13.8 ksi) for C18600-TB00 — about 3.2 times as much. Tensile strength is 360 MPa (52.2 ksi) vs 250 MPa (36.3 ksi).
Which condition does FabDigit quote by default, H02 or TB00?
TM04 is the default C18600 condition in the FabDigit quote flow (neither H02 nor TB00). 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, C18600-H02 or C18600-TB00?
C18600-H02, by a small margin. Both rate poor for machinability — 20/100 against 15/100 for C18600-TB00; for welding the order is C18600-TB00 first (fair, 45/100) then C18600-H02 (fair, 40/100).
