Copper Alloy C48500-H04 vs C48500-O60
Copper Alloy · C48500 temper comparison
C48500-H04 and C48500-O60 are two conditions of the same copper alloy grade, C48500: H04 (full hard) versus O60 (soft annealed). The chemistry is identical, so every difference below comes from the condition. C48500-H04 is the stronger of the two: yield strength 390 MPa (56.6 ksi) against 165 MPa (23.9 ksi) for C48500-O60, about 136% more; tensile strength follows at 540 MPa (78.3 ksi) vs 380 MPa (55.1 ksi). In exchange, C48500-O60 is the more ductile: elongation 42% versus 13% for C48500-H04, and C48500-H04 is harder (150 HB vs 80 HB). C48500-O60 runs hotter in service (200°C vs 150°C continuous). On the shop floor, C48500-O60 welds better (32 vs 20 out of 100).
C48500-H04Choose it when strength drives the design.
C48500-O60Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C48500-H04 vs C48500-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.

C48500-H04 vs C48500-O60 — frequently asked
Is C48500-H04 stronger than C48500-O60?
Yes. C48500-H04 has a typical yield strength of 390 MPa (56.6 ksi) against 165 MPa (23.9 ksi) for C48500-O60 — about 136% more. Tensile strength is 540 MPa (78.3 ksi) vs 380 MPa (55.1 ksi).
Which condition does FabDigit quote by default, H04 or O60?
H02 is the default C48500 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.
Which welds better, C48500-H04 or C48500-O60?
C48500-O60. Its weldability rates poor (32/100) against poor (20/100) for C48500-H04.
