Copper Alloy C48200-H02 vs C48200-M30
Copper Alloy · C48200 temper comparison
C48200-H02 and C48200-M30 are two conditions of the same copper alloy grade, C48200: H02 (half hard) versus M30 (as hot extruded). The chemistry is identical, so every difference below comes from the condition. C48200-H02 is the stronger of the two: yield strength 345 MPa (50 ksi) against 172 MPa (24.9 ksi) for C48200-M30, about 101% more; tensile strength follows at 483 MPa (70.1 ksi) vs 379 MPa (55 ksi). In exchange, C48200-M30 is the more ductile: elongation 40% versus 20% for C48200-H02, and C48200-H02 is harder (140 HB vs 100 HB).
C48200-H02Choose it when strength drives the design.
C48200-M30Choose it when the part is bent, formed or impact-loaded.
C48200-H02 vs C48200-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.

C48200-H02 vs C48200-M30 — frequently asked
Is C48200-H02 stronger than C48200-M30?
Yes. C48200-H02 has a typical yield strength of 345 MPa (50 ksi) against 172 MPa (24.9 ksi) for C48200-M30 — about 101% more. Tensile strength is 483 MPa (70.1 ksi) vs 379 MPa (55 ksi).
Which condition does FabDigit quote by default, H02 or M30?
M30 is the default C48200 condition in the FabDigit quote flow. 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-H02 or C48200-M30?
C48200-H02, by a small margin. Both rate very good for machinability — 75/100 against 70/100 for C48200-M30.
