Copper Alloy C34200-H06 vs C34200-M20
Copper Alloy · C34200 temper comparison
C34200-H06 and C34200-M20 are two conditions of the same copper alloy grade, C34200: H06 (extra hard) versus M20 (as hot rolled). The chemistry is identical, so every difference below comes from the condition. C34200-H06 is the stronger of the two: yield strength 450 MPa (65.3 ksi) against 150 MPa (21.8 ksi) for C34200-M20, about 3.0 times as much; tensile strength follows at 545 MPa (79 ksi) vs 360 MPa (52.2 ksi). In exchange, C34200-M20 is the more ductile: elongation 40% versus 6% for C34200-H06, and C34200-H06 is harder (165 HB vs 80 HB). C34200-M20 runs hotter in service (250°C vs 175°C continuous).
C34200-H06Choose it when strength drives the design.
C34200-M20Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C34200-H06 vs C34200-M20: 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.

C34200-H06 vs C34200-M20 — frequently asked
Is C34200-H06 stronger than C34200-M20?
Yes. C34200-H06 has a typical yield strength of 450 MPa (65.3 ksi) against 150 MPa (21.8 ksi) for C34200-M20 — about 3.0 times as much. Tensile strength is 545 MPa (79 ksi) vs 360 MPa (52.2 ksi).
Which condition does FabDigit quote by default, H06 or M20?
H02 is the default C34200 condition in the FabDigit quote flow (neither H06 nor M20). 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, C34200-H06 or C34200-M20?
C34200-H06, by a small margin. Both rate excellent for machinability — 92/100 against 85/100 for C34200-M20.
