Copper Alloy C11100-H02 vs C11100-H08

Copper Alloy · C11100 temper comparison

C11100-H02 and C11100-H08 are two conditions of the same copper alloy grade, C11100: H02 (half hard) versus H08 (spring hard). The chemistry is identical, so every difference below comes from the condition. C11100-H08 is the stronger of the two: yield strength 355 MPa (51.5 ksi) against 250 MPa (36.3 ksi) for C11100-H02, about 42% more; tensile strength follows at 380 MPa (55.1 ksi) vs 300 MPa (43.5 ksi). In exchange, C11100-H02 is the more ductile: elongation 14% versus 3% for C11100-H08, and C11100-H08 is harder (110 HB vs 82 HB).

C11100-H02 vs C11100-H08 — frequently asked

Is C11100-H08 stronger than C11100-H02?

Yes. C11100-H08 has a typical yield strength of 355 MPa (51.5 ksi) against 250 MPa (36.3 ksi) for C11100-H02 — about 42% more. Tensile strength is 380 MPa (55.1 ksi) vs 300 MPa (43.5 ksi).

Which condition does FabDigit quote by default, H02 or H08?

H04 is the default C11100 condition in the FabDigit quote flow (neither H02 nor H08). 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, C11100-H02 or C11100-H08?

C11100-H08. Its machinability rates fair (35/100) against poor (30/100) for C11100-H02.
