Copper Alloy CuAg0.04P Cast vs CuAg0.04P-M
Copper Alloy · CuAg0.04P temper comparison
CuAg0.04P Cast and CuAg0.04P-M are two conditions of the same copper alloy grade, CuAg0.04P: Cast (as cast) versus M (thermomechanically controlled processed). The chemistry is identical, so every difference below comes from the condition. CuAg0.04P-M is the stronger of the two: yield strength 100 MPa (14.5 ksi) against 55 MPa (7.98 ksi) for CuAg0.04P Cast, about 82% more; tensile strength follows at 220 MPa (31.9 ksi) vs 160 MPa (23.2 ksi). CuAg0.04P-M is harder — 57 HB against 42 HB for CuAg0.04P Cast — which matters for wear surfaces and threads. On the shop floor, CuAg0.04P-M forms better (very good vs good).
CuAg0.04P-MChoose it when strength drives the design, or when surface hardness matters.
CuAg0.04P Cast vs CuAg0.04P-M: 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.

CuAg0.04P Cast vs CuAg0.04P-M — frequently asked
Is CuAg0.04P-M stronger than CuAg0.04P Cast?
Yes. CuAg0.04P-M has a typical yield strength of 100 MPa (14.5 ksi) against 55 MPa (7.98 ksi) for CuAg0.04P Cast — about 82% more. Tensile strength is 220 MPa (31.9 ksi) vs 160 MPa (23.2 ksi).
Which condition does FabDigit quote by default, Cast or M?
R240 is the default CuAg0.04P condition in the FabDigit quote flow (neither Cast nor M). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
When should I choose CuAg0.04P Cast over CuAg0.04P-M?
Pick CuAg0.04P-M when strength drives the design, or when surface hardness matters.
