Copper Alloy C10200-H04 vs C10200-O
Copper Alloy · C10200 temper comparison
C10200-H04 and C10200-O are two conditions of the same copper alloy grade, C10200: H04 (full hard) versus O (annealed). The chemistry is identical, so every difference below comes from the condition. C10200-H04 is the stronger of the two: yield strength 310 MPa (45 ksi) against 69 MPa (10 ksi) for C10200-O, about 4.5 times as much; tensile strength follows at 345 MPa (50 ksi) vs 221 MPa (32.1 ksi). In exchange, C10200-O is the more ductile: elongation 45% versus 6% for C10200-H04, and C10200-H04 is harder (95 HB vs 45 HB). C10200-O runs hotter in service (250°C vs 120°C continuous).

C10200-OChoose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C10200-H04 vs C10200-O: 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.

C10200-H04 vs C10200-O — frequently asked
Is C10200-H04 stronger than C10200-O?
Yes. C10200-H04 has a typical yield strength of 310 MPa (45 ksi) against 69 MPa (10 ksi) for C10200-O — about 4.5 times as much. Tensile strength is 345 MPa (50 ksi) vs 221 MPa (32.1 ksi).
Which condition does FabDigit quote by default, H04 or O?
O is the default C10200 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, C10200-H04 or C10200-O?
C10200-H04, by a small margin. Both rate poor for machinability — 28/100 against 22/100 for C10200-O.
