Copper Alloy C53800-H01 vs C53800-H02

Copper Alloy · C53800 temper comparison

C53800-H01 and C53800-H02 are two conditions of the same copper alloy grade, C53800: H01 (quarter hard) versus H02 (half hard). The chemistry is identical, so every difference below comes from the condition. C53800-H02 is the stronger of the two: yield strength 380 MPa (55.1 ksi) against 290 MPa (42.1 ksi) for C53800-H01, about 31% more; tensile strength follows at 480 MPa (69.6 ksi) vs 420 MPa (60.9 ksi). In exchange, C53800-H01 is the more ductile: elongation 25% versus 15% for C53800-H02, and C53800-H02 is harder (145 HB vs 118 HB).

C53800-H01 vs C53800-H02 — frequently asked

Is C53800-H02 stronger than C53800-H01?

Yes. C53800-H02 has a typical yield strength of 380 MPa (55.1 ksi) against 290 MPa (42.1 ksi) for C53800-H01 — about 31% more. Tensile strength is 480 MPa (69.6 ksi) vs 420 MPa (60.9 ksi).

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

H04 is the default C53800 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.

Which is easier to machine, C53800-H01 or C53800-H02?

C53800-H02, by a small margin. Both rate very good for machinability — 80/100 against 75/100 for C53800-H01.
