Copper Alloy C67600-H06 vs C67600-M30

Copper Alloy · C67600 temper comparison

C67600-H06 and C67600-M30 are two conditions of the same copper alloy grade, C67600: H06 (extra hard) versus M30 (as hot extruded). The chemistry is identical, so every difference below comes from the condition. C67600-H06 is the stronger of the two: yield strength 470 MPa (68.2 ksi) against 200 MPa (29 ksi) for C67600-M30, about 135% more; tensile strength follows at 680 MPa (98.6 ksi) vs 470 MPa (68.2 ksi). In exchange, C67600-M30 is the more ductile: elongation 30% versus 9% for C67600-H06, and C67600-H06 is harder (190 HB vs 110 HB). C67600-M30 runs hotter in service (200°C vs 150°C continuous).

C67600-H06Choose it when strength drives the design.

C67600-M30Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

C67600-H06 vs C67600-M30 — frequently asked

Is C67600-H06 stronger than C67600-M30?

Yes. C67600-H06 has a typical yield strength of 470 MPa (68.2 ksi) against 200 MPa (29 ksi) for C67600-M30 — about 135% more. Tensile strength is 680 MPa (98.6 ksi) vs 470 MPa (68.2 ksi).

Which condition does FabDigit quote by default, H06 or M30?

H02 is the default C67600 condition in the FabDigit quote flow (neither H06 nor M30). 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, C67600-H06 or C67600-M30?

C67600-H06, by a small margin. Both rate good for machinability — 62/100 against 55/100 for C67600-M30.
