Copper Alloy C19200-H04 vs C19200-O60
Copper Alloy · C19200 temper comparison
C19200-H04 and C19200-O60 are two conditions of the same copper alloy grade, C19200: H04 (full hard) versus O60 (soft annealed). The chemistry is identical, so every difference below comes from the condition. C19200-H04 is the stronger of the two: yield strength 355 MPa (51.5 ksi) against 85 MPa (12.3 ksi) for C19200-O60, about 4.2 times as much; tensile strength follows at 380 MPa (55.1 ksi) vs 260 MPa (37.7 ksi). In exchange, C19200-O60 is the more ductile: elongation 40% versus 4% for C19200-H04, and C19200-H04 is harder (105 HB vs 50 HB). C19200-O60 runs hotter in service (250°C vs 200°C continuous).
C19200-H04Choose it when strength drives the design.
C19200-O60Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C19200-H04 vs C19200-O60: 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.

C19200-H04 vs C19200-O60 — frequently asked
Is C19200-H04 stronger than C19200-O60?
Yes. C19200-H04 has a typical yield strength of 355 MPa (51.5 ksi) against 85 MPa (12.3 ksi) for C19200-O60 — about 4.2 times as much. Tensile strength is 380 MPa (55.1 ksi) vs 260 MPa (37.7 ksi).
Which condition does FabDigit quote by default, H04 or O60?
H55 is the default C19200 condition in the FabDigit quote flow (neither H04 nor O60). 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.
When should I choose C19200-H04 over C19200-O60?
Pick C19200-H04 when strength drives the design. Pick C19200-O60 when the part is bent, formed or impact-loaded, or when the part sees heat.
