Copper Alloy C48200-H04 vs C48200-M11
Copper Alloy · C48200 temper comparison
C48200-H04 and C48200-M11 are two conditions of the same copper alloy grade, C48200: H04 (full hard) versus M11 (as forged and quenched). The chemistry is identical, so every difference below comes from the condition. C48200-H04 is the stronger of the two: yield strength 400 MPa (58 ksi) against 205 MPa (29.7 ksi) for C48200-M11, about 95% more; tensile strength follows at 517 MPa (75 ksi) vs 448 MPa (65 ksi). In exchange, C48200-M11 is the more ductile: elongation 30% versus 15% for C48200-H04, and C48200-H04 is harder (160 HB vs 115 HB).
C48200-H04Choose it when strength drives the design.
C48200-M11Choose it when the part is bent, formed or impact-loaded.
C48200-H04 vs C48200-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.

C48200-H04 vs C48200-M11 — frequently asked
Is C48200-H04 stronger than C48200-M11?
Yes. C48200-H04 has a typical yield strength of 400 MPa (58 ksi) against 205 MPa (29.7 ksi) for C48200-M11 — about 95% more. Tensile strength is 517 MPa (75 ksi) vs 448 MPa (65 ksi).
Which condition does FabDigit quote by default, H04 or M11?
M30 is the default C48200 condition in the FabDigit quote flow (neither H04 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, C48200-H04 or C48200-M11?
C48200-H04, by a small margin. Both rate very good for machinability — 75/100 against 70/100 for C48200-M11.
