Copper Alloy C33200-H04 vs C33200-H55
Copper Alloy · C33200 temper comparison
C33200-H04 and C33200-H55 are two conditions of the same copper alloy grade, C33200: H04 (full hard) versus H55 (light drawn). The chemistry is identical, so every difference below comes from the condition. C33200-H04 is the stronger of the two: yield strength 370 MPa (53.7 ksi) against 240 MPa (34.8 ksi) for C33200-H55, about 54% more; tensile strength follows at 470 MPa (68.2 ksi) vs 380 MPa (55.1 ksi). In exchange, C33200-H55 is the more ductile: elongation 30% versus 12% for C33200-H04, and C33200-H04 is harder (130 HB vs 95 HB).
C33200-H04Choose it when strength drives the design.
C33200-H55Choose it when the part is bent, formed or impact-loaded.
C33200-H04 vs C33200-H55: 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.

C33200-H04 vs C33200-H55 — frequently asked
Is C33200-H04 stronger than C33200-H55?
Yes. C33200-H04 has a typical yield strength of 370 MPa (53.7 ksi) against 240 MPa (34.8 ksi) for C33200-H55 — about 54% more. Tensile strength is 470 MPa (68.2 ksi) vs 380 MPa (55.1 ksi).
Which condition does FabDigit quote by default, H04 or H55?
H80 is the default C33200 condition in the FabDigit quote flow (neither H04 nor H55). 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 C33200-H04 over C33200-H55?
Pick C33200-H04 when strength drives the design. Pick C33200-H55 when the part is bent, formed or impact-loaded.
