Copper Alloy C63600-H01 vs C63600-M30
Copper Alloy · C63600 temper comparison
C63600-H01 and C63600-M30 are two conditions of the same copper alloy grade, C63600: H01 (quarter hard) versus M30 (as hot extruded). The chemistry is identical, so every difference below comes from the condition. C63600-H01 is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 185 MPa (26.8 ksi) for C63600-M30, about 105% more; tensile strength follows at 485 MPa (70.3 ksi) vs 420 MPa (60.9 ksi). In exchange, C63600-M30 is the more ductile: elongation 40% versus 25% for C63600-H01, and C63600-H01 is harder (145 HB vs 108 HB). C63600-M30 runs hotter in service (300°C vs 230°C continuous).
C63600-H01Choose it when strength drives the design.
C63600-M30Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C63600-H01 vs C63600-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.

C63600-H01 vs C63600-M30 — frequently asked
Is C63600-H01 stronger than C63600-M30?
Yes. C63600-H01 has a typical yield strength of 380 MPa (55.1 ksi) against 185 MPa (26.8 ksi) for C63600-M30 — about 105% more. Tensile strength is 485 MPa (70.3 ksi) vs 420 MPa (60.9 ksi).
Which condition does FabDigit quote by default, H01 or M30?
O61 is the default C63600 condition in the FabDigit quote flow (neither H01 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, C63600-H01 or C63600-M30?
C63600-H01, by a small margin. Both rate fair for machinability — 45/100 against 38/100 for C63600-M30.
