Copper Alloy C50700-H01 vs C50700-H02

Copper Alloy · C50700 temper comparison

C50700-H01 and C50700-H02 are two conditions of the same copper alloy grade, C50700: H01 (quarter hard) versus H02 (half hard). The chemistry is identical, so every difference below comes from the condition. C50700-H02 is the stronger of the two: yield strength 340 MPa (49.3 ksi) against 270 MPa (39.2 ksi) for C50700-H01, about 26% more; tensile strength follows at 405 MPa (58.7 ksi) vs 350 MPa (50.8 ksi). In exchange, C50700-H01 is the more ductile: elongation 25% versus 14% for C50700-H02, and C50700-H02 is harder (120 HB vs 103 HB).

C50700-H01 vs C50700-H02 — frequently asked

Is C50700-H02 stronger than C50700-H01?

Yes. C50700-H02 has a typical yield strength of 340 MPa (49.3 ksi) against 270 MPa (39.2 ksi) for C50700-H01 — about 26% more. Tensile strength is 405 MPa (58.7 ksi) vs 350 MPa (50.8 ksi).

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

H08 is the default C50700 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, C50700-H01 or C50700-H02?

C50700-H02, by a small margin. Both rate poor for machinability — 30/100 against 25/100 for C50700-H01.
