Copper Alloy C80700-M01 vs C80700-M05

Copper Alloy · C80700 temper comparison

C80700-M01 and C80700-M05 are two conditions of the same copper alloy grade, C80700: M01 (as sand cast) versus M05 (as plaster cast). The chemistry is identical, so every difference below comes from the condition. C80700-M05 is the stronger of the two: yield strength 70 MPa (10.2 ksi) against 62 MPa (8.99 ksi) for C80700-M01, about 13% more; tensile strength follows at 185 MPa (26.8 ksi) vs 172 MPa (24.9 ksi). C80700-M05 is harder — 48 HB against 44 HB for C80700-M01 — which matters for wear surfaces and threads.

C80700-M05Choose it when strength drives the design, or when surface hardness matters.
