Copper Alloy C19100-M10 vs C19100-M11
Copper Alloy · C19100 temper comparison
C19100-M10 and C19100-M11 are two conditions of the same copper alloy grade, C19100: M10 (as hot forged and air cooled) versus M11 (as forged and quenched). The chemistry is identical, so every difference below comes from the condition. C19100-M10 is the stronger of the two: yield strength 215 MPa (31.2 ksi) against 140 MPa (20.3 ksi) for C19100-M11, about 54% more; tensile strength follows at 350 MPa (50.8 ksi) vs 310 MPa (45 ksi). In exchange, C19100-M11 is the more ductile: elongation 35% versus 25% for C19100-M10, and C19100-M10 is harder (90 HB vs 72 HB). C19100-M10 runs hotter in service (250°C vs 200°C continuous) and C19100-M10 conducts heat better (172 W/m·K vs 150 W/m·K).
C19100-M10Choose it when strength drives the design, or when the part sees heat.
C19100-M11Choose it when the part is bent, formed or impact-loaded.
C19100-M10 vs C19100-M11: 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-M10 vs C19100-M11 — frequently asked
Is C19100-M10 stronger than C19100-M11?
Yes. C19100-M10 has a typical yield strength of 215 MPa (31.2 ksi) against 140 MPa (20.3 ksi) for C19100-M11 — about 54% more. Tensile strength is 350 MPa (50.8 ksi) vs 310 MPa (45 ksi).
Which condition does FabDigit quote by default, M10 or M11?
TF00 is the default C19100 condition in the FabDigit quote flow (neither M10 nor M11). 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-M10 over C19100-M11?
Pick C19100-M10 when strength drives the design, or when the part sees heat. Pick C19100-M11 when the part is bent, formed or impact-loaded.
