Copper Alloy CuAg0.07-H01 vs CuAg0.07-O60
Copper Alloy · CuAg0.07 temper comparison
CuAg0.07-H01 and CuAg0.07-O60 are two conditions of the same copper alloy grade, CuAg0.07: H01 (quarter hard) versus O60 (soft annealed). The chemistry is identical, so every difference below comes from the condition. CuAg0.07-H01 is the stronger of the two: yield strength 215 MPa (31.2 ksi) against 70 MPa (10.2 ksi) for CuAg0.07-O60, about 3.1 times as much; tensile strength follows at 275 MPa (39.9 ksi) vs 220 MPa (31.9 ksi). In exchange, CuAg0.07-O60 is the more ductile: elongation 48% versus 25% for CuAg0.07-H01, and CuAg0.07-H01 is harder (70 HB vs 42 HB). CuAg0.07-H01 runs hotter in service (300°C vs 250°C continuous).
CuAg0.07-H01Choose it when strength drives the design, or when the part sees heat.
CuAg0.07-O60Choose it when the part is bent, formed or impact-loaded.
CuAg0.07-H01 vs CuAg0.07-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.

CuAg0.07-H01 vs CuAg0.07-O60 — frequently asked
Is CuAg0.07-H01 stronger than CuAg0.07-O60?
Yes. CuAg0.07-H01 has a typical yield strength of 215 MPa (31.2 ksi) against 70 MPa (10.2 ksi) for CuAg0.07-O60 — about 3.1 times as much. Tensile strength is 275 MPa (39.9 ksi) vs 220 MPa (31.9 ksi).
Which condition does FabDigit quote by default, H01 or O60?
H04 is the default CuAg0.07 condition in the FabDigit quote flow (neither H01 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 CuAg0.07-H01 over CuAg0.07-O60?
Pick CuAg0.07-H01 when strength drives the design, or when the part sees heat. Pick CuAg0.07-O60 when the part is bent, formed or impact-loaded.
