Copper Alloy C36200-H04 vs C36200-M30
Copper Alloy · C36200 temper comparison
C36200-H04 and C36200-M30 are two conditions of the same copper alloy grade, C36200: H04 (full hard) versus M30 (as hot extruded). The chemistry is identical, so every difference below comes from the condition. C36200-H04 is the stronger of the two: yield strength 370 MPa (53.7 ksi) against 125 MPa (18.1 ksi) for C36200-M30, about 196% more; tensile strength follows at 450 MPa (65.3 ksi) vs 340 MPa (49.3 ksi). In exchange, C36200-M30 is the more ductile: elongation 50% versus 15% for C36200-H04, and C36200-H04 is harder (135 HB vs 78 HB). C36200-M30 runs hotter in service (250°C vs 180°C continuous).
C36200-H04Choose it when strength drives the design.
C36200-M30Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C36200-H04 vs C36200-M30: 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.

C36200-H04 vs C36200-M30 — frequently asked
Is C36200-H04 stronger than C36200-M30?
Yes. C36200-H04 has a typical yield strength of 370 MPa (53.7 ksi) against 125 MPa (18.1 ksi) for C36200-M30 — about 196% more. Tensile strength is 450 MPa (65.3 ksi) vs 340 MPa (49.3 ksi).
Which condition does FabDigit quote by default, H04 or M30?
H02 is the default C36200 condition in the FabDigit quote flow (neither H04 nor M30). 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, C36200-H04 or C36200-M30?
C36200-H04, by a small margin. Both rate excellent for machinability — 100/100 against 95/100 for C36200-M30.
