Copper Alloy C84100-M01 vs C84100-M05

Copper Alloy · C84100 temper comparison

C84100-M01 and C84100-M05 are two conditions of the same copper alloy grade, C84100: M01 (as sand cast) versus M05 (as plaster cast). The chemistry is identical, so every difference below comes from the condition. C84100-M05 is the stronger of the two: yield strength 97 MPa (14.1 ksi) against 90 MPa (13.1 ksi) for C84100-M01, about 8% more; tensile strength follows at 221 MPa (32.1 ksi) vs 207 MPa (30 ksi). C84100-M05 is harder — 55 HB against 52 HB for C84100-M01 — which matters for wear surfaces and threads.

C84100-M05Choose it when strength drives the design, or when surface hardness matters.
