Copper Alloy C22000-H01 vs C22000-H03

Copper Alloy · C22000 temper comparison

C22000-H01 and C22000-H03 are two conditions of the same copper alloy grade, C22000: H01 (quarter hard) versus H03 (three-quarter hard). The chemistry is identical, so every difference below comes from the condition. C22000-H03 is the stronger of the two: yield strength 310 MPa (45 ksi) against 215 MPa (31.2 ksi) for C22000-H01, about 44% more; tensile strength follows at 370 MPa (53.7 ksi) vs 305 MPa (44.2 ksi). In exchange, C22000-H01 is the more ductile: elongation 35% versus 8% for C22000-H03, and C22000-H03 is harder (115 HB vs 90 HB).

C22000-H01Choose it when the part is bent, formed or impact-loaded.

C22000-H03Choose it when strength drives the design.

C22000-H01 vs C22000-H03 — frequently asked

Is C22000-H03 stronger than C22000-H01?

Yes. C22000-H03 has a typical yield strength of 310 MPa (45 ksi) against 215 MPa (31.2 ksi) for C22000-H01 — about 44% more. Tensile strength is 370 MPa (53.7 ksi) vs 305 MPa (44.2 ksi).

Which condition does FabDigit quote by default, H01 or H03?

O is the default C22000 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.

Which is easier to machine, C22000-H01 or C22000-H03?

C22000-H01. Its machinability rates fair (35/100) against poor (30/100) for C22000-H03; for welding the order is C22000-H03 first (fair, 50/100) then C22000-H01 (fair, 45/100).
