Copper Alloy C11100-H01 vs C11100-H02

Copper Alloy · C11100 temper comparison

C11100-H01 and C11100-H02 are two conditions of the same copper alloy grade, C11100: H01 (quarter hard) versus H02 (half hard). The chemistry is identical, so every difference below comes from the condition. C11100-H02 is the stronger of the two: yield strength 250 MPa (36.3 ksi) against 220 MPa (31.9 ksi) for C11100-H01, about 14% more; tensile strength follows at 300 MPa (43.5 ksi) vs 275 MPa (39.9 ksi). In exchange, C11100-H01 is the more ductile: elongation 25% versus 14% for C11100-H02, and C11100-H02 is harder (82 HB vs 70 HB).

C11100-H01Choose it when the part is bent, formed or impact-loaded.

C11100-H02Choose it when strength drives the design.

C11100-H01 vs C11100-H02 — frequently asked

Is C11100-H02 stronger than C11100-H01?

Yes. C11100-H02 has a typical yield strength of 250 MPa (36.3 ksi) against 220 MPa (31.9 ksi) for C11100-H01 — about 14% more. Tensile strength is 300 MPa (43.5 ksi) vs 275 MPa (39.9 ksi).

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

H04 is the default C11100 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 C11100-H01 over C11100-H02?

Pick C11100-H01 when the part is bent, formed or impact-loaded. Pick C11100-H02 when strength drives the design.
