Copper Alloy C17450-TB00 vs C17450-TM06
Copper Alloy · C17450 temper comparison
C17450-TB00 and C17450-TM06 are two conditions of the same copper alloy grade, C17450: TB00 (solution heat treated) versus TM06 (mill hardened, extra hard). The chemistry is identical, so every difference below comes from the condition. C17450-TM06 is the stronger of the two: yield strength 655 MPa (95 ksi) against 170 MPa (24.7 ksi) for C17450-TB00, about 3.9 times as much; tensile strength follows at 760 MPa (110 ksi) vs 330 MPa (47.9 ksi). In exchange, C17450-TB00 is the more ductile: elongation 35% versus 10% for C17450-TM06, and C17450-TM06 is harder (222 HB vs 200 HB). C17450-TM06 conducts heat better (200 W/m·K vs 110 W/m·K).
C17450-TB00Choose it when the part is bent, formed or impact-loaded.
C17450-TM06Choose it when strength drives the design.
C17450-TB00 vs C17450-TM06: 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.

C17450-TB00 vs C17450-TM06 — frequently asked
Is C17450-TM06 stronger than C17450-TB00?
Yes. C17450-TM06 has a typical yield strength of 655 MPa (95 ksi) against 170 MPa (24.7 ksi) for C17450-TB00 — about 3.9 times as much. Tensile strength is 760 MPa (110 ksi) vs 330 MPa (47.9 ksi).
Which condition does FabDigit quote by default, TB00 or TM06?
TM04 is the default C17450 condition in the FabDigit quote flow (neither TB00 nor TM06). 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.
When should I choose C17450-TB00 over C17450-TM06?
Pick C17450-TB00 when the part is bent, formed or impact-loaded. Pick C17450-TM06 when strength drives the design.
