Copper Alloy C94400-M01 vs C94400-M05

Copper Alloy · C94400 temper comparison

C94400-M01 and C94400-M05 are two conditions of the same copper alloy grade, C94400: M01 (as sand cast) versus M05 (as plaster cast). The chemistry is identical, so every difference below comes from the condition. C94400-M05 is the stronger of the two: yield strength 117 MPa (17 ksi) against 110 MPa (16 ksi) for C94400-M01, about 6% more; tensile strength follows at 234 MPa (33.9 ksi) vs 221 MPa (32.1 ksi). C94400-M05 is the more ductile: elongation 20% versus 18% for C94400-M01, and C94400-M05 is harder (60 HB vs 55 HB).

C94400-M05Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
