Copper Alloy C17460-TB00 vs C17460-TM02
Copper Alloy · C17460 temper comparison
C17460-TB00 and C17460-TM02 are two conditions of the same copper alloy grade, C17460: TB00 (solution heat treated) versus TM02 (mill hardened, half hard). The chemistry is identical, so every difference below comes from the condition. C17460-TM02 is the stronger of the two: yield strength 550 MPa (79.8 ksi) against 170 MPa (24.7 ksi) for C17460-TB00, about 3.2 times as much; tensile strength follows at 660 MPa (95.7 ksi) vs 340 MPa (49.3 ksi). In exchange, C17460-TB00 is the more ductile: elongation 28% versus 14% for C17460-TM02, and C17460-TM02 is harder (185 HB vs 95 HB). C17460-TM02 runs hotter in service (340°C vs 150°C continuous) and C17460-TM02 conducts heat better (230 W/m·K vs 130 W/m·K). On the shop floor, C17460-TM02 machines more easily (fair vs poor).
C17460-TB00Choose it when the part is bent, formed or impact-loaded.
C17460-TM02Choose it when strength drives the design, or when the part sees heat.
C17460-TB00 vs C17460-TM02: 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.

C17460-TB00 vs C17460-TM02 — frequently asked
Is C17460-TM02 stronger than C17460-TB00?
Yes. C17460-TM02 has a typical yield strength of 550 MPa (79.8 ksi) against 170 MPa (24.7 ksi) for C17460-TB00 — about 3.2 times as much. Tensile strength is 660 MPa (95.7 ksi) vs 340 MPa (49.3 ksi).
Which condition does FabDigit quote by default, TB00 or TM02?
TF00 is the default C17460 condition in the FabDigit quote flow (neither TB00 nor TM02). 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, C17460-TB00 or C17460-TM02?
C17460-TM02. Its machinability rates fair (45/100) against poor (30/100) for C17460-TB00; for welding the order is C17460-TB00 first (fair, 50/100) then C17460-TM02 (fair, 45/100).
