Copper Alloy C33200-H04 vs C33200-OS015

Copper Alloy · C33200 temper comparison

C33200-H04 and C33200-OS015 are two conditions of the same copper alloy grade, C33200: H04 (full hard) versus OS015 (annealed to 0.015 mm grain size). 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 125 MPa (18.1 ksi) for C33200-OS015, about 196% more; tensile strength follows at 470 MPa (68.2 ksi) vs 345 MPa (50 ksi). In exchange, C33200-OS015 is the more ductile: elongation 50% versus 12% for C33200-H04, and C33200-H04 is harder (130 HB vs 70 HB). C33200-OS015 runs hotter in service (200°C vs 150°C continuous).

C33200-H04Choose it when strength drives the design.

C33200-OS015Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

C33200-H04 vs C33200-OS015 — frequently asked

Is C33200-H04 stronger than C33200-OS015?

Yes. C33200-H04 has a typical yield strength of 370 MPa (53.7 ksi) against 125 MPa (18.1 ksi) for C33200-OS015 — about 196% more. Tensile strength is 470 MPa (68.2 ksi) vs 345 MPa (50 ksi).

Which condition does FabDigit quote by default, H04 or OS015?

H80 is the default C33200 condition in the FabDigit quote flow (neither H04 nor OS015). 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, C33200-H04 or C33200-OS015?

C33200-H04, by a small margin. Both rate very good for machinability — 82/100 against 77/100 for C33200-OS015.
