Copper Alloy C87610-M04 vs C87610-M07

Copper Alloy · C87610 temper comparison

C87610-M04 and C87610-M07 are two conditions of the same copper alloy grade, C87610: M04 (as pressure die cast) versus M07 (as continuous cast). The chemistry is identical, so every difference below comes from the condition. C87610-M07 is the stronger of the two: yield strength 195 MPa (28.3 ksi) against 180 MPa (26.1 ksi) for C87610-M04, about 8% more. C87610-M07 is harder — 65 HRB against 60 HRB for C87610-M04 — which matters for wear surfaces and threads.

C87610-M07Choose it when strength drives the design, or when surface hardness matters.

C87610-M04 vs C87610-M07 — frequently asked

Is C87610-M07 stronger than C87610-M04?

Yes. C87610-M07 has a typical yield strength of 195 MPa (28.3 ksi) against 180 MPa (26.1 ksi) for C87610-M04 — about 8% more. Tensile strength is 420 MPa (60.9 ksi) vs 400 MPa (58 ksi).

Which condition does FabDigit quote by default, M04 or M07?

M01 is the default C87610 condition in the FabDigit quote flow (neither M04 nor M07). 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 C87610-M04 over C87610-M07?

Pick C87610-M07 when strength drives the design, or when surface hardness matters.
