Copper Alloy C19210-H01 vs C19210-H03
Copper Alloy · C19210 temper comparison
C19210-H01 and C19210-H03 are two conditions of the same copper alloy grade, C19210: H01 (quarter hard) versus H03 (three-quarter hard). The chemistry is identical, so every difference below comes from the condition. C19210-H03 is the stronger of the two: yield strength 315 MPa (45.7 ksi) against 225 MPa (32.6 ksi) for C19210-H01, about 40% more; tensile strength follows at 345 MPa (50 ksi) vs 280 MPa (40.6 ksi). In exchange, C19210-H01 is the more ductile: elongation 15% versus 7% for C19210-H03, and C19210-H03 is harder (118 HV vs 95 HV). C19210-H01 runs hotter in service (230°C vs 200°C continuous).
C19210-H01Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C19210-H03Choose it when strength drives the design.
C19210-H01 vs C19210-H03: 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.

C19210-H01 vs C19210-H03 — frequently asked
Is C19210-H03 stronger than C19210-H01?
Yes. C19210-H03 has a typical yield strength of 315 MPa (45.7 ksi) against 225 MPa (32.6 ksi) for C19210-H01 — about 40% more. Tensile strength is 345 MPa (50 ksi) vs 280 MPa (40.6 ksi).
Which condition does FabDigit quote by default, H01 or H03?
H04 is the default C19210 condition in the FabDigit quote flow (neither H01 nor H03). 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 C19210-H01 over C19210-H03?
Pick C19210-H01 when the part is bent, formed or impact-loaded, or when the part sees heat. Pick C19210-H03 when strength drives the design.
