Copper Alloy C15500-H01 vs C15500-H02

Copper Alloy · C15500 temper comparison

C15500-H01 and C15500-H02 are two conditions of the same copper alloy grade, C15500: H01 (quarter hard) versus H02 (half hard). The chemistry is identical, so every difference below comes from the condition. C15500-H02 is the stronger of the two: yield strength 270 MPa (39.2 ksi) against 205 MPa (29.7 ksi) for C15500-H01, about 32% more; tensile strength follows at 310 MPa (45 ksi) vs 270 MPa (39.2 ksi). In exchange, C15500-H01 is the more ductile: elongation 25% versus 14% for C15500-H02, and C15500-H02 is harder (88 HB vs 70 HB). C15500-H01 runs hotter in service (300°C vs 275°C continuous).

C15500-H01Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

C15500-H02Choose it when strength drives the design.

C15500-H01 vs C15500-H02 — frequently asked

Is C15500-H02 stronger than C15500-H01?

Yes. C15500-H02 has a typical yield strength of 270 MPa (39.2 ksi) against 205 MPa (29.7 ksi) for C15500-H01 — about 32% more. Tensile strength is 310 MPa (45 ksi) vs 270 MPa (39.2 ksi).

Which condition does FabDigit quote by default, H01 or H02?

H04 is the default C15500 condition in the FabDigit quote flow (neither H01 nor H02). 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 C15500-H01 over C15500-H02?

Pick C15500-H01 when the part is bent, formed or impact-loaded, or when the part sees heat. Pick C15500-H02 when strength drives the design.
