Copper Alloy C87610-M01 vs C87610-M05
Copper Alloy · C87610 temper comparison
C87610-M01 and C87610-M05 are two conditions of the same copper alloy grade, C87610: M01 (as sand cast) versus M05 (as plaster cast). The chemistry is identical, so every difference below comes from the condition. C87610-M05 is the stronger of the two: yield strength 190 MPa (27.6 ksi) against 170 MPa (24.7 ksi) for C87610-M01, about 12% more; tensile strength follows at 415 MPa (60.2 ksi) vs 380 MPa (55.1 ksi). C87610-M05 is harder — 110 HB against 100 HB for C87610-M01 — which matters for wear surfaces and threads.
C87610-M05Choose it when strength drives the design, or when surface hardness matters.
C87610-M01 vs C87610-M05: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all copper alloy grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.
