Copper Alloy C14500-H01 vs C14500-M11
Copper Alloy · C14500 temper comparison
C14500-H01 and C14500-M11 are two conditions of the same copper alloy grade, C14500: H01 (quarter hard) versus M11 (as forged and quenched). The chemistry is identical, so every difference below comes from the condition. C14500-H01 is the stronger of the two: yield strength 240 MPa (34.8 ksi) against 76 MPa (11 ksi) for C14500-M11, about 3.2 times as much; tensile strength follows at 285 MPa (41.3 ksi) vs 234 MPa (33.9 ksi). In exchange, C14500-M11 is the more ductile: elongation 40% versus 22% for C14500-H01, and C14500-H01 is harder (78 HB vs 55 HB).
C14500-H01Choose it when strength drives the design.
C14500-M11Choose it when the part is bent, formed or impact-loaded.
C14500-H01 vs C14500-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.

C14500-H01 vs C14500-M11 — frequently asked
Is C14500-H01 stronger than C14500-M11?
Yes. C14500-H01 has a typical yield strength of 240 MPa (34.8 ksi) against 76 MPa (11 ksi) for C14500-M11 — about 3.2 times as much. Tensile strength is 285 MPa (41.3 ksi) vs 234 MPa (33.9 ksi).
Which condition does FabDigit quote by default, H01 or M11?
H02 is the default C14500 condition in the FabDigit quote flow (neither H01 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.
Which is easier to machine, C14500-H01 or C14500-M11?
C14500-M11, by a small margin. Both rate excellent for machinability — 92/100 against 85/100 for C14500-H01; for welding the order is C14500-M11 first (poor, 30/100) then C14500-H01 (poor, 25/100).
