Copper Alloy C94100-M01 vs C94100-M05

Copper Alloy · C94100 temper comparison

C94100-M01 and C94100-M05 are two conditions of the same copper alloy grade, C94100: M01 (as sand cast) versus M05 (as plaster cast). The chemistry is identical, so every difference below comes from the condition. C94100-M05 is the stronger of the two: yield strength 96 MPa (13.9 ksi) against 86 MPa (12.5 ksi) for C94100-M01, about 12% more; tensile strength follows at 193 MPa (28 ksi) vs 179 MPa (26 ksi). C94100-M05 is harder — 58 HB against 55 HB for C94100-M01 — which matters for wear surfaces and threads.

C94100-M05Choose it when strength drives the design, or when surface hardness matters.
