Copper Alloy C91600-M01 vs C91600-M02

Copper Alloy · C91600 temper comparison

C91600-M01 and C91600-M02 are two conditions of the same copper alloy grade, C91600: M01 (as sand cast) versus M02 (as centrifugally cast). The chemistry is identical, so every difference below comes from the condition. C91600-M02 is the stronger of the two: yield strength 180 MPa (26.1 ksi) against 152 MPa (22 ksi) for C91600-M01, about 18% more. In exchange, C91600-M01 is the more ductile: elongation 16% versus 12% for C91600-M02, and C91600-M02 is harder (105 HB vs 90 HB).

C91600-M01Choose it when the part is bent, formed or impact-loaded.

C91600-M02Choose it when strength drives the design.

C91600-M01 vs C91600-M02 — frequently asked

Is C91600-M02 stronger than C91600-M01?

Yes. C91600-M02 has a typical yield strength of 180 MPa (26.1 ksi) against 152 MPa (22 ksi) for C91600-M01 — about 18% more. Tensile strength is 320 MPa (46.4 ksi) vs 310 MPa (45 ksi).

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

M07 is the default C91600 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 C91600-M01 over C91600-M02?

Pick C91600-M01 when the part is bent, formed or impact-loaded. Pick C91600-M02 when strength drives the design.
