Copper Alloy C93800-M01 vs C93800-M02

Copper Alloy · C93800 temper comparison

C93800-M01 and C93800-M02 are two conditions of the same copper alloy grade, C93800: M01 (as sand cast) versus M02 (as centrifugally cast). The chemistry is identical, so every difference below comes from the condition. C93800-M02 is the stronger of the two: yield strength 124 MPa (18 ksi) against 110 MPa (16 ksi) for C93800-M01, about 13% more; tensile strength follows at 221 MPa (32.1 ksi) vs 207 MPa (30 ksi). In exchange, C93800-M01 is the more ductile: elongation 18% versus 12% for C93800-M02, and C93800-M02 is harder (60 HB vs 55 HB).

C93800-M01Choose it when the part is bent, formed or impact-loaded.

C93800-M02Choose it when strength drives the design.

C93800-M01 vs C93800-M02 — frequently asked

Is C93800-M02 stronger than C93800-M01?

Yes. C93800-M02 has a typical yield strength of 124 MPa (18 ksi) against 110 MPa (16 ksi) for C93800-M01 — about 13% more. Tensile strength is 221 MPa (32.1 ksi) vs 207 MPa (30 ksi).

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

M07 is the default C93800 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 C93800-M01 over C93800-M02?

Pick C93800-M01 when the part is bent, formed or impact-loaded. Pick C93800-M02 when strength drives the design.
