Copper Alloy C93500-M01 vs C93500-M02

Copper Alloy · C93500 temper comparison

C93500-M01 and C93500-M02 are two conditions of the same copper alloy grade, C93500: M01 (as sand cast) versus M02 (as centrifugally cast). The chemistry is identical, so every difference below comes from the condition. C93500-M02 is the stronger of the two: yield strength 131 MPa (19 ksi) against 110 MPa (16 ksi) for C93500-M01, about 19% more; tensile strength follows at 234 MPa (33.9 ksi) vs 221 MPa (32.1 ksi). C93500-M02 is harder — 23 HRB against 20 HRB for C93500-M01 — which matters for wear surfaces and threads.

C93500-M02Choose it when strength drives the design, or when surface hardness matters.

C93500-M01 vs C93500-M02 — frequently asked

Is C93500-M02 stronger than C93500-M01?

Yes. C93500-M02 has a typical yield strength of 131 MPa (19 ksi) against 110 MPa (16 ksi) for C93500-M01 — about 19% more. Tensile strength is 234 MPa (33.9 ksi) vs 221 MPa (32.1 ksi).

Which condition does FabDigit quote by default, M01 or M02?

M07 is the default C93500 condition in the FabDigit quote flow (neither M01 nor M02). 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 C93500-M01 over C93500-M02?

Pick C93500-M02 when strength drives the design, or when surface hardness matters.
