Copper Alloy C62581-M10 vs C62581-M30

Copper Alloy · C62581 temper comparison

C62581-M10 and C62581-M30 are two conditions of the same copper alloy grade, C62581: M10 (as hot forged and air cooled) versus M30 (as hot extruded). The chemistry is identical, so every difference below comes from the condition. C62581-M10 is the stronger of the two: yield strength 448 MPa (65 ksi) against 414 MPa (60 ksi) for C62581-M30, about 8% more. In exchange, C62581-M30 is the more ductile: elongation 5% versus 4% for C62581-M10, and C62581-M10 is harder (23 HRC vs 21 HRC).

C62581-M10Choose it when strength drives the design.

C62581-M30Choose it when the part is bent, formed or impact-loaded.

C62581-M10 vs C62581-M30 — frequently asked

Is C62581-M10 stronger than C62581-M30?

Yes. C62581-M10 has a typical yield strength of 448 MPa (65 ksi) against 414 MPa (60 ksi) for C62581-M30 — about 8% more. Tensile strength is 772 MPa (112 ksi) vs 758 MPa (110 ksi).

Which condition does FabDigit quote by default, M10 or M30?

TQ50 is the default C62581 condition in the FabDigit quote flow (neither M10 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.

When should I choose C62581-M10 over C62581-M30?

Pick C62581-M10 when strength drives the design. Pick C62581-M30 when the part is bent, formed or impact-loaded.
