Copper Alloy C14200-H02 vs C14200-H04
Copper Alloy · C14200 temper comparison
C14200-H02 and C14200-H04 are two conditions of the same copper alloy grade, C14200: H02 (half hard) versus H04 (full hard). The chemistry is identical, so every difference below comes from the condition. C14200-H04 is the stronger of the two: yield strength 310 MPa (45 ksi) against 250 MPa (36.3 ksi) for C14200-H02, about 24% more; tensile strength follows at 350 MPa (50.8 ksi) vs 295 MPa (42.8 ksi). In exchange, C14200-H02 is the more ductile: elongation 14% versus 6% for C14200-H04, and C14200-H04 is harder (95 HB vs 85 HB). C14200-H02 runs hotter in service (290°C vs 200°C continuous). On the shop floor, C14200-H02 machines more easily (fair vs poor).
C14200-H02Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.
C14200-H04Choose it when strength drives the design.
C14200-H02 vs C14200-H04: 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.

C14200-H02 vs C14200-H04 — frequently asked
Is C14200-H04 stronger than C14200-H02?
Yes. C14200-H04 has a typical yield strength of 310 MPa (45 ksi) against 250 MPa (36.3 ksi) for C14200-H02 — about 24% more. Tensile strength is 350 MPa (50.8 ksi) vs 295 MPa (42.8 ksi).
Which condition does FabDigit quote by default, H02 or H04?
OS050 is the default C14200 condition in the FabDigit quote flow (neither H02 nor H04). 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, C14200-H02 or C14200-H04?
C14200-H02. Its machinability rates fair (40/100) against poor (30/100) for C14200-H04.
