Copper Alloy C19100-M11 vs C19100-TH04
Copper Alloy · C19100 temper comparison
C19100-M11 and C19100-TH04 are two conditions of the same copper alloy grade, C19100: M11 (as forged and quenched) versus TH04 (TD04 and precipitation hardened). The chemistry is identical, so every difference below comes from the condition. C19100-TH04 is the stronger of the two: yield strength 500 MPa (72.5 ksi) against 140 MPa (20.3 ksi) for C19100-M11, about 3.6 times as much; tensile strength follows at 550 MPa (79.8 ksi) vs 310 MPa (45 ksi). In exchange, C19100-M11 is the more ductile: elongation 35% versus 8% for C19100-TH04, and C19100-TH04 is harder (165 HB vs 72 HB). C19100-TH04 runs hotter in service (300°C vs 200°C continuous) and C19100-TH04 conducts heat better (178 W/m·K vs 150 W/m·K).
C19100-M11Choose it when the part is bent, formed or impact-loaded.
C19100-TH04Choose it when strength drives the design, or when the part sees heat.
C19100-M11 vs C19100-TH04: 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.

C19100-M11 vs C19100-TH04 — frequently asked
Is C19100-TH04 stronger than C19100-M11?
Yes. C19100-TH04 has a typical yield strength of 500 MPa (72.5 ksi) against 140 MPa (20.3 ksi) for C19100-M11 — about 3.6 times as much. Tensile strength is 550 MPa (79.8 ksi) vs 310 MPa (45 ksi).
Which condition does FabDigit quote by default, M11 or TH04?
TF00 is the default C19100 condition in the FabDigit quote flow (neither M11 nor TH04). 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 C19100-M11 over C19100-TH04?
Pick C19100-M11 when the part is bent, formed or impact-loaded. Pick C19100-TH04 when strength drives the design, or when the part sees heat.
